If the Kb of a weak base is 4.2x10^9, then the pKb is _______.
Ammonium ion, NH4+, is a (weak acid, conjugate base, OR spectator ion).
5.0 grams of HOCI, when dissolved in 100 mL water, will have a pH value (about equal to, less than, OR more than 7.0).
Calculate the pH of the following solutions: Data Table of Ka values attached on the last page. Use as needed:
