	ChemLab - Techniques - Titration
		A titration is a method of analysis that will allow you to determine the precise endpoint of a reaction and therefore the precise quantity of reactant in the titration flask.
		Use this, the concentration of the titrant, and the stoichiometry of the titration reaction to calculate the number of moles of reactant in your analyte solution.
		Titration with a pH meter follows the same procedure as a titration with an indicator, except that the endpoint is detected by a rapid change in pH, rather than the color change of an indicator.

		For example, a given volume of a solution of unknown acidity may be titrated with a base of known concentration until complete neutralization has occurred.
		Titrations can also be used to determine the number of acidic or basic groups in an unknown compound.
		A specific weight of the compound is titrated with a known concentration of acid or base until the equivalence point has been reached.

		Step 4, you now titrate the solutions by moving the scroll bar instead of opening the cork of the buret to set the drop speed of the solution from the buret.
		When you reach the expected equivalence point, move the scroll bar to the left to reduce the drop speed of the solution; you may want to add one drop at a time to find the exact point.
		The difference between the titration curve and an indicator is that the titration curve can show how accurately the experiment was performed ö The steeper the slope of the titration curve at the equivalence point is, the more accurate the data are.

	Titration Project, Part 1
		The technique known as titration is an analytical method commonly used in chemistry laboratories for determining the quantity or concentration of a substance in a solution.
		In a titration, an analyte -- the substance whose quantity or concentration is to be determined -- is reacted with a carefully controlled volume of solution of accurately-known concentration called a standard solution.
		In a typical acid-base titration experiment, the solution containing the analyte (an acid of unknown identity and/or concentration) is placed into a container, and the titrant (a base of accurately-known concentration) is slowly added from the buret in small increments (see Figure 1).

	Acid Base Titration-Comp.1-WWW (Site not responding. Last check: )
		In the titration of a strong acid with a strong base, the pH of the solution at the equivalence point is established by the dissociation of water, as shown in Equation 5.
		The equivalence point of the titration is found by drawing a vertical line through the midpoint of the steep portion of the curve and then dividing that portion of the curve into two equal parts.
		A typical curve for the titration of a weak acid with a strong base is shown in Figure 2.

	TITRATION
		Titration to optimal effect is the central principle in the treatment of diseases with medications.
		This principle is seldom effectively applied to the treatment of chronic pain with opioids, because of irrational fears of respiratory depression, addiction, and ever-present threat of regulatory sanctions.
		The conception that tolerance to the pain controlling effects of opioids doesn’t or shouldn’t occur is, in an academic sense, essentially sound, but can be misleading to the practitioner when a patient’s pain levels increase after a period of stability.

	Titraton Systems (Site not responding. Last check: )
		In 1855, the German chemist, Friedrich Mohrn, defined titration as the "weighing without scale" method, because this process allows determination of the concentration of a sample without using complex instrumentation.
		A manual titration requires high accuracy and precision, both in the preparation of the material, and the use of different precisely dosed reagents.
		Titration, moreover, can be of different types: potentiometric, amperometric, spectrophotometric, etc., depending on the properties of the monitored system.

	Titration
		In titration, one solution (solution 1) is added to another solution (solution 2) until a chemical reaction between the components in the solutions has run to completion.
		Figure 1 Setup for a Typical Titration In a typical titration, the titrant in the buret is added to the solution in the Erlenmeyer flask until the indicator changes color to show that the reaction is complete.
		Titration reveals that 11.6 mL of 3.0 M sulfuric acid are required to neutralize the sodium hydroxide in 25.00 mL of NaOH solution.

	SparkNotes: Titrations: Acid-Base Titrations
		Titration is a general class of experiment where a known property of one solution is used to infer an unknown property of another solution.
		A titration curve is drawn by plotting data attained during a titration, titrant volume on the x-axis and pH on the y-axis.
		The titration of a base with an acid produces a flipped-over version of the titration curve of an acid with a base.

	volanal (Site not responding. Last check: )
		This process is called titration and the solution in the buret is called the titrant.
		Continue the titration until the reaction is complete; that is, until the amount of reactant added is exactly the amount required to react with all the constituent being analyzed.
		Place the solution that is to be titrated in an Erlenmeyer flask and add 3-5 drops of the appropriate indicator.

	pH curves (titration curves)
		When you carry out a simple acid-base titration, you use an indicator to tell you when you have the acid and alkali mixed in exactly the right proportions to "neutralise" each other.
		Similarly, if you titrate sodium hydroxide solution with ethanoic acid, at the equivalence point the pure sodium ethanoate formed has a slightly alkaline pH because the ethanoate ion is slightly basic.
		The reason that it is difficult to do these titrations is discussed on the page about indicators.

	Investigating Titration Curves
		Titration is a process which consists of the gradual addition of a standard solution to a measured quantity of a solution of unknown concentration.
		In an acid-base titration, the point at which the moles of hydroxide ion and the moles of hydronium ions are equal is the equivalence point.
		To develop a titration curve it is probably not necessary to calibrate the pH probe.

	Triprotic Acid Titration Examples
		Second, the titration curves are calculated using a working equation for a triprotic acid being titrated with a strong base.
		Phosphoric acid is a good example of a titration where the first two equivalence points, corresponding to base reaction with the first and second protons, respectively, are clearly visible.
		Of more importance to the prediction of the shape of the titration curve is the fact that there are several species in solution at the pH where the second equivalence point should be reached.

	Titration Curve
		Frequently, during a titration it is also useful to monitor the progress of the titration with a graph.
		The easiest titration curve to work with is obtained from the titration of a strong monoprotic acid with a strong base.
		Titration curves are useful because they are good graphic representations of exactly what occurs during a titration process.

	Titrating Oil - Collaborative Biodiesel Tutorial
		Titration is done by reacting a small sample of free fatty acid (which happens to be in a ml of waste oil) with a measured amount of lye, and using pH to tell us when the FFA is all used up.
		The titration performs the lye/free fatty acid reaction on a very small scale, and we use pH to measure it (somebody before us has previously figured out which pH change indicates that this reaction is complete, and it's at pH 8.5, the color change point of phenolpthalein indicator.
		For every titration, you'll be measuring tiny amounts of this solution with a syringe- so I like to measure it out of a small jar or a beaker, so I dont have to dip the syringe into the main liter bottle and contaminate the bottle.

	Automatic process titration system (US4018565)
		An automatic titration system and method in which the titrant is generated electrolytically and a two-position slider type ceramic sample valve, reliably, accurately and repetitively obtains a volumetric sample from a process loop and introduces it to a titration cell containing a generator or working compartment and an auxiliary compartment separated by a porous frit.
		The progress of the titration is monitored by indicating and reference electrodes in the titration cell connected to an appropriate endpoint indicator, output of which is compared to a known setpoint corresponding to the titration endpoint.
		The total charge delivered to the generator and auxiliary electrodes during titration is measured by a timer or integrator and read out as a trend output signal.
