General Sciences Sample First Exercise Propanoic Acid Solution
... Thus the statement is true. II-2-b) Propanoic acid is a weak acid, so Cacid ≠ [H3O+] then C1 ≠ [H3O+]S1. But pH1 = - log [H3O+]1 then log C1 ≠ pH1. Thus the statement is false. II-2-c) F = 100; for strong acids, upon dilution by 100 folds the pH increases by 2 units. If this acid were strong then pH ...
