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

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

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it
