Question #55318

Write a net ionic equation for the overall reaction that occurs when aqueous solutions of hydrosulfuric acid (H2S) and sodium hydroxide are combined. Is this correct?

H2S + NaOH = H2O + Na2S unbalanced
H2S + 2 NaOH = 2 H2O + Na2S balanced

H2S(aq) + 2Na(aq) + 2 OH- (aq) = 2 Na (aq) + S 2- (aq) + 2H2O (l)
H2S(aq) + 2 OH- (aq) = S 2- (aq) + 2H2O (l)

Expert's answer

H₂S + NaOH = H₂O + Na₂S unbalanced
H₂S + 2 NaOH = 2 H₂O + Na₂S balanced

H₂S(aq) + 2Na(aq) + 2 OH^- (aq) = 2 Na (aq) + S^2- (aq) + 2H₂O (l)
H₂S(aq) + 2 OH^- (aq) = S^2- (aq) + 2H₂O (l)
Answer:
Yes, these equations are correct.
Sodium hydroxide and sodium sulfide are electrolytes, so they form ions in water solution. Hydrosulfuric acid (H₂S) isn’t electrolyte, so it doesn’t form ions in water solution.
