IV. Percent Ionization

IV. Percent Ionization. Instead of characterizing a weak acid by its K a , we can calculate how much it ionizes. The concentration of ionized acid is simply equal to the [H + ] at equilibrium. IV. Sample Problem. Find the % ionization of a 0.200 M acetic acid solution if its pK a = 4.74.

Strong and Weak Acids and Bases

Strong and Weak Acids and Bases. Pg 560-578. The strength of an acid is determined by the extent to which it ionizes, its percent ionization, not the concentration of the acid, the concentration of its hydronium ions, or its ability to react with a metal. Strong Acid.

Acids and Bases

Acids and Bases. pH Scale. Indicates the concentration of hydronium ions in a solution. Goes from 0 (acidic) to 14 (basic) 7 is considered neutral (water). Litmus Paper. Used to determine the pH of a solution. Red litmus paper= red in acid and neutrals, blue in base.

Neutralization of an acid or base.

Neutralization of an acid or base. Mixing acids and bases. ~creates water H 3 O + + OH - ? 2 H 2 O this is called neutralizing the solution a neutralized solution is no longer dangerous. The point where neutralization is complete is called the equivalence point. Salts.
