what is the effect of dilution on the [H+] and percent ionization of a weak acid
< Homework 42 Weak Acid / Weak Base Equilibrium + Percent Ionization 2 of 8 Constants Periodic Table Percent ionization can be used to quantify the extent of ionization of an acid in solution and is defined by the following formula for the acid HA: A certain weak acid, HA, has a Ka value of 4.7x10-7 Percent ionization=1 _HA ionized HA initial x 100% Part A Percent ionization increases with increasing K. Strong acids, for which K, is very large,...
