Question

The spectator ions in the reaction between aqueous perchloric acid and aqueous barium hydroxide are ________. OH- and ClO4- H , OH- , ClO4-, and Ba2 H and OH- H and Ba2 ClO4- and Ba2

Answer 1

Answer:

ClO4-, and Ba2+.

Explanation:

A spectator ion is an ion that exists as a reactant and a product in a chemical equation.

Equation of the reaction.

2HClO4 + Ba(OH)2 --> Ba(ClO4)2 + 2H2O

ClO4- + OH- --> 2ClO4- + H2O
