Cations of weak bases are ACIDIC. They donate H to water making the weak + base and H O3which reduces the pH of the solution: NH 4+ (aq) .... + .... 2 O .... ---> ....NH 3aq) .... + .... H3O (aq) + Donates H weak base ACIDIC solution Cations of strong bases are NEUTRAL. They do not interact with water: Na (aq) .... + .... H2O .... ---> .... No Reaction Anions of weak acids are BASIC. They accept H from water making the weak - acid and OH which increases the pH of the solution: F (aq) .... + .... 2 O .... ---> .... HF(aq) .... + .... OH (aq) + Accepts H weak acid BASIC solution Anions of strong acids are NEUTRAL. They do not interact with water: Cl (aq) .... + .... H2O .... ---> .... No Reaction Most anions of polyprotic acids are BASIC, accepting H from water, although some act as acids and donate a proton to water. Cations of transition metal atoms are ACIDIC. In solution they are surrounded + by 4-6 water molecules. One of the water molecules breaks up, giving off H and making the solution acidic.
