Question

Compound is HMnO4

Compound X will undergo either a precipitation reaction (a) or an acid-base reaction (b) Please complete only the appropriate reaction with compound X. In other words, you will only answer one part of this question. a. If compound X will undergo a precipitation reaction, react it with a compound that would form an insoluble precipitate. Write the balance molecular, complete ionic, and net ionic reactions. (b) If compound X is an acid, react with a strong base. Write the balanced molecular, complete ionic, and net ionic reactions.

Explanation / Answer

17.b.

Compound X is HMnO4 which is gven as weak acid.

Reaction of a weak acid and a strong base:

HMnO4 + NaOH -----------> NaMnO4 + H2O

Complete ionic equation:

HMnO4 + Na+ + OH- ------------> NaMnO4 + H2O

Net ionic equation:

HMnO4 + OH- --------------> MnO4- + H2O
