Question

When solid zinc hydroxide is in equilibrium with its ions, the ratio of zinc ion to hydroxide ion is 1:2 *Is this true or false?

Answer 1

Let us first consider the reaction of zinc and hydoxide ion :

• Zn^2+(s) + 2OH^-1(aq) ↔ Zn(OH)2 (aq)

ratio> 1 : 2 :1

From the above, we can see that the ratio of zinc ion to hydroxide ion is 1:2, the answer is True .
