# Answer to Question #55318 in General Chemistry for susan

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)

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

H2S(aq) + 2Na(aq) + 2 OH- (aq) = 2 Na (aq) + S2- (aq) + 2H2O (l)
H2S(aq) + 2 OH- (aq) = S2- (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.
