Answer:
Hydrosulfuric acid:H2S and potassium hydroxide:KOh.
The molecular equation is
H2S(aq) + 2KOH(aq) -------> K2S(aq) + 2H2O(l)
The ionic equation is
H2S(aq) + 2K^+(aq) + 2OH^-(aq) ------> 2K^+(aq) +S^-2(aq) +2H2O (l)
Here H2S is weak electrolyte, so it doesn't forms ions in water, therefore K^+(aq) is the spectator ion.
The final net ionic equation is
H2S(aq) + 2OH^-(aq) ------> S^-2(aq) + 2H2O(l)
Please let me know if you have any doubt. Thanks.
