Write a net ionic equation for the overall reaction that occurs when aqueous solutions of hydrosulfuric acid (H2S) and sodium hy
erica [24]

Answer:

H2S(g) + 2OH^-(aq) -------->  S^2-(aq) + 2H2O(l)

Explanation:

We know that the net ionic equation shows the major reaction that occurs in the reaction system.

The molecular reaction equation is;

H2S(g) + 2NaOH(aq) ------> Na2S(aq) + 2H2O(l)

The complete ionic equation is;

H2S(g) + 2Na^+(aq) + 2OH^-(aq) --------> 2Na^+(aq) + S^2-(aq) + 2H2O(l)

Net ionic equation;

H2S(g) + 2OH^-(aq) -------->  S^2-(aq) + 2H2O(l)
