	Strong acid - Wikipedia, the free encyclopedia
		This generally means that in aqueous solution at standard temperature and pressure, the concentration of hydronium ions is equal to the concentration of strong acid introduced to the solution.
		While strong acids are generally assumed to be the most corrosive, this is not always true.
		The difference separating the acid dissociation constants of strong acids from all other acids is so great that this is a reasonable demarkation.

	Hydrochloric acid - Wikipedia, the free encyclopedia
		It is a strong acid, the major component of gastric acid and of wide industrial use.
		Strong acid titrants are useful because they give more distinct endpoints in a titration, making the titration more precise.
		Hydrochloric acid is a fundamental chemical, and as such it is used for a large number of small-scale applications, such as leather processing, household cleaning, and building construction.

	Acid - Wikipedia, the free encyclopedia
		The strength of an acid may be understood by this defintion by the stability of hydronium and the solvated conjugate base upon dissociation.
		Strong acids are dangerous, causing severe burns for even minor contact.
		Nitric acid, sulfuric acid, and perchloric acid are all strong acids, whereas nitrous acid, sulfurous acid and hypochlorous acid are all weak.

	Acid/Base Strength (Site not responding. Last check: 2007-09-18)
		When a strong acid of a given concentration in a dilute aqueous solution ionizes, the resulting concentration of hydronium ions and the resulting concentration of the conjugate base are equal to the original concentration of the acid.
		In order to calculate the concentration of the weak acid at equilibrium, the fact that a decrease in the concentration of the acid corresponds to an increase both in the concentration of the hydronium ions and of the conjugate base must be used.
		The conjugate acid of a weak base is a strong acid and the conjugate base of a strong acid is a weak base.

	Acid Base Reactions (Site not responding. Last check: 2007-09-18)
		The strength of an acid is determined by the extent to which it donates its proton in the presence of a common base such as water.
		Strong acids essentially dissociate (lose their protons) completely and have relatively large dissociation constants, whereas weak acids dissociate only slightly and have relatively small dissociation constants.
		Strong acids dissociate completely such that if HA in equation [5.14] is a strong acid, the reaction goes completely to the right and [HA] essentially equals zero.

	Re: what is the difference between strong acid and concentrated acid?
		How strong this needs to be will vary from solvent to solvent, but we normally think of a strong acid as one that is completely dissociated in water.
		Glacial acetic acid is a concentrated weak acid, and industrial sulfuric acid (about 98% by weight, the other 2% is water) is a concentrated strong acid.
		Even strong acids are not completely dissociated when the concentration is too high: concentrated hydrochloric acid, even though it is only 12-13 moles per liter in water, is concentrated enough that there are irritating fumes of HCl gas above the acid.

	Acid Strength
		Strong acids have mostly ions in solution, therefore the bonds holding H and A together must be weak.
		Acids or bases with strong bonds exist predominately as molecules in solutions and are called "weak" acids or bases.
		Acids or bases with weak bonds easily dissociate into ions and are called "strong" acids or bases.

	The Other Strong Acid: Nitric
		Nitric acid is also a key component in the manufacturing of adipic acid and terephthalic acid.
		Dilute nitric acid from the process in Figure 1 is fed to the concentration unit as shown in Figure 2 along with concentrated sulfuric acid (usually 60-67% by weight).
		The addition of sulfuric acid is necessary due to the azeotrope formed between nitric acid and water.

	Acid-Base
		When we represent an acid in reaction, we often use simply HA (or HB) where the H is the proton that is released in reaction with bases and the A (or B) is the rest of the molecule.
		Similarly, Strong bases are levelled to the strongest base that can exist in water, OH Thus, any intrinsic differences in the strengths of strong acids (or bases) are not detectable in water since they can't exist in aqueous solution.
		An indicator is a weak acid that is coloured and whose colour is different from that of its conjugate base (or vice versa).

	Acid Strength
		Also in any acid base reaction, the strong acid and strong base always proceeds to the weaker acid and base since the strong acid and base are better able to function as acid and base.
		The weaker the acid the stronger is the bond between its Hydrogens and the rest of the molecule.
		If we compared acid strength with acids where the atoms bonded to Hydrogen were in the same period, the difference in the size of the atoms would not be significant.

		A strong acid is an acidic compound which ionizes completely or almost completely in aqueous solution.
		Differentiating between the strength of the strong acids in aqueous solutions is impossible, because the concentration of hydrogen ions is always equal to the concentration of the acid.
		Only through replacing water with concentrated Acetic acid as a diluent one can observe and measure diference in the tendency to dissociate the proton ion, among the strong acids.

		Describe the form of the titration curves for titration of a strong acid by a strong base, a weak acid by a strong base, or a weak base by a strong acid.
		For a reaction between an acid and a base, a titration is useful for measuring the pH at various points throughout the reaction.
		The gradual slope results from a buffer solution being produced by the addition of the strong acid or base, which resists rapid change in pH until the added acid or base exceeds the buffer's capacity and the rapid pH change occurs near the equivalence point.

		The explanation for why strong electrolytes behaved the way they did was first suggested in 1904, but was not proven until 1923.
		Certain acids are considered to be strong, which means they are dissociated 100% in solution.
		There are a few others which are "almost" strong and sometimes a textbook author will include one in his or her own list.

	Chemical Sciences: Acidity of Solutions of Strong Acids
		A strong acid, by definition, is an acid that is completely ionized in aqueous solution, that is, an acid which produces one or more protons for every acid molecule originally present.
		Therefore, in an aqueous solution of a strong acid, acidity is essentially determined by the concentration of strong acid alone.
		Only when the concentration of strong acid present is very low does the autoionization of water become a comparable or dominant contributor to the solution pH.

		You should memorize the strong acids because there are only a few and then all the rest are weak.
		Also, for aqueous solution, a strong acid has a very large equilibrium constant, so large it cannot be measured.
		As a practical matter, if you have memorized the small number of strong acids, all the rest must be weak.
