In the Bronsted-Lowry theory of acids and bases an acid is a proton (hydrogen) donor and a base is a proton acceptor. Substances that readily behave in this way to completion are characterized as "strong" acids or bases. However if the acidic or ...
An acid-base reaction usually (but not always) deals with a transfer of ionized hydrogen atoms (protons), which occurs from an acidic reactant to a basic reactant in aqueous solution. In the simplest case, both reactants are monoprotic, so they donate/accept...

Buffering Solution: A buffering solution maintains a constant pH by eliminating the effects of a change in the concentration of H+ ions. This is achieved through two equilibrium reactions. Answer and Explanation:1 Buffers require a weak acid/base wh...
Is HCl classified as a strong acid, strong base, weak acid, or weak base? For each of the following, classify the substance as a strong acid, strong base, weak acid, or weak base (or perhaps not acidic or basic). Then determine the pH of the so...
