The overall salt does not donate protons, the CH3NH3+ ion does (to form H3O+) when the salt is dissociated in water. sodium cyanide =NaCN CN-is the conjugatebase of the weak acidHCN therefore the solution isbasic with a pH > 7 calcium perchlorate =Ca (ClO4)2 Ca2+is the cation of the strong base,Ca (OH)2. It is a base by the same principle as NH3 is a base which is ; A free electron pair on N atom atracts a watter protone to form NH4+ and OH- . Get control of 2022! The perchlorate ion ClO4- is the conjugate base of a strong acid (HClO4) thus the ClO4- ion has weak to none basic properties. The relative strength of an acid or base is the extent to which it ionizes when dissolved in water.
