Write a balanced equation for the following mechanism for the formation of H_xWO

Question

Write a balanced equation for the following mechanism for the formation of H_xWO_3 assuming X=1

Hydrogen ions from the solution of HCl diffuse into the solid releasing zinc ions bound at the surface in the course of reduction by metallic zinc. In this view, hydrogen gas is a side product of a reaction between zinc and acid. Write a balanced equation for the following mechanism for the formation of H_xWO_3 assuming X=1

Hydrogen ions from the solution of HCl diffuse into the solid releasing zinc ions bound at the surface in the course of reduction by metallic zinc. In this view, hydrogen gas is a side product of a reaction between zinc and acid.

Hydrogen ions from the solution of HCl diffuse into the solid releasing zinc ions bound at the surface in the course of reduction by metallic zinc. In this view, hydrogen gas is a side product of a reaction between zinc and acid.

Explanation / Answer

Answer – We are given the hydrogen ions from the solution of HCl diffuse into the solid releasing zinc ions bound at the surface in the course of reduction by metallic zinc. In this view, hydrogen gas is a side product of a reaction between zinc and acid, so balanced reaction is -

2 HCl(aq) + Zn(s) -----> ZnCl2(aq) + H2(g)
