	SparkNotes: SAT Chemistry: Conjugate Acid-Base Pairs
		Conjugate acid-base pairs are compounds that differ by the presence of one proton, or H
		All acids have a conjugate base, which is formed when their proton has been donated; likewise, all bases have a conjugate acid, formed after they have accepted a proton.
		The pH of a solution is calculated as the negative logarithm in base 10 of the hydronium ion concentration—it is an expression of the molar concentration of H

	Conjugate Pairs
		A natural consequence of the Brønsted-Lowry definitions of acids and bases, perhaps a diabolical one, is that we end up with a very interesting relationship between acids and bases.
		When a base accepts a proton, the resulting chemical is called the conjugate acid of that original base.
		Being able to recognize conjugate pairs of acids and bases becomes important dealing with comparisons between the strengths of acids and bases, buffered solutions, and the hydrolysis of various salts.

	ACIDS AND BASES IN ORGANIC CHEMISTRY
		You should also know that the conjugate base of a Bronsted acid is the species formed when a proton is lost from that acid (e.g., hydroxide ion is the conjugate base of water; water is the conjugate base of the hydronium ion).
		Similarly, the conjugate acid of a Bronsted base is the species formed when that base is protonated.Thus, water is the conjugate acid of hydroxide ion, and hydronium ion is the conjugate acid of water.
		The conjugate base of a carboxylic acid is a carboxylate anion.

	Acid-Base Equilibria
		The relative strengths of an acid and its conjugate base are reciprocally related; the stronger an acid, the weaker its conjugate base, and the weaker an acid, the stronger its conjugate base.
		In general, bases: (a) turn blue litmus to red; (b) react with metals to produce hydrogen gas; (c) are insoluble in water (d) have a sour taste; (e) have a bitter taste.
		The conjugate base of an acid: (a) is the molecule or ion left after the acid accepts a proton; (b) is not stable under most conditions; (c) is a stronger acid than the original acid; (d) is the molecule or ion left after the acid donates a proton; (e) cannot itself be an acid.

	Acid Base Reactions (Site not responding. Last check: )
		The conjugate acid-base pairs are H3O+ / H2O and C6H5OH / C6H5O - in equation [5.2] and H3O+ / H2O and NH4+ / NH3 in equation [5.3].
		Likewise the strength of a base is determined by the extent to which it accepts a proton in the presence of a common acid such as water.
		Strong bases dissociate completely such that if BOH in equation [5.16] is a strong base, the reaction goes completely to the right and [BOH] essentially equals zero (this can be demonstrated in a similar manner to example 5.5).

		To determine the conjugate base of a molecule, determine the structure after the removal of a proton (H+).
		Since the chlorine of the conjugate base of the second acid is closer to the negative charge, it (the conjugate base) is more stable than the first, where the chlorine atom is much further from the negative charge.
		The conjugate base which has a conjugate acid that has a very positive pKa value is a weak conjugate base.

		In this part of the pH scale, the acid and conjugate base are both present in significant concentrations and the solution resists changes in pH.
		Here the volume of base added is half that required to reach the equivalence point and half the acetic acid has been converted to the conjugate base, acetate ion.
		In this region, the acid and its conjugate base are present in similar (within a factor of 10) concentrations.

	Theories of acids and bases
		A base is a proton (hydrogen ion) acceptor.
		The water is acting as an acid, and its conjugate base is the hydroxide ion.
		The hydroxide ion is a base and water is its conjugate acid.

	NetLogo Models Library: Buffer
		This range is determined by the concentrations of the weak acid and its conjugate base.
		In this model we are assuming that 2% of the original acid molecules are dissociated into 2 conjugate base molecules and 2 hydronium molecules.
		When hydronium and conjugate base collide, they have a high probability of transforming into a weak acid molecule and a water molecule.

	A - Glossary of chemical terms
		In the Lowry-Brønsted theory of acids and bases (1923), the definition was extended to one in which an acid is a proton donor (a Brønsted acid), and a base is a proton acceptor (a Brønsted base).
		For example, acetate ion is the conjugate base of acetic acid, and ammonium ion is the conjugate acid of ammonia.
		As the acid of a conjugate acid/base pair becomes weaker, its conjugate base becomes stronger and vice versa.

	Organic Acids and Bases
		The most common acid and base classification for organic chemists is the Bronsted-Lowry acid and base definition.
		The main thing to remember is that, in general, the strength of an acid is based loosely upon the stability of its conjugate base.
		Since most acids are neutrally charged (that is, have no charge) the conjugate base of most acids will be negatively charged (because the acid has lost an H+).

	Acid @ iCookClub.com
		BrÃ¸nsted-Lowry: According to this definition, an acid is a proton donor and a base is a proton acceptor.
		Lewis: According to this definition, an acid is an electron-pair acceptor and a base is an electron-pair donor.
		The strength of an acid may be understood by this defintion by the stability of hydronium and the solvated conjugate base upon dissociation.
