Which of the following statements is true concerning a 0.1 M solution of Na₂S and a 0.1 M solution of NaHS? For H₂S,Ka₁ = 1.0 × 10^-7 and Ka₂ = 1.3 × 10^-13. A)Both solutions are neutral. B)The sodium hydrogen sulfide solution is the more basic. C)Both solutions have the same pH. D)The sodium sulfide solution is the more basic. E)Both the solutions are acidic.

The sodium sulfide (Na2S) solution is more basic due to the presence of S2- ions, which are strong bases. Sodium hydrogen sulfide (NaHS) partially dissociates into H+ and HS- ions, making the solution slightly acidic or less basic compared to Na2S. The given Ka values indicate the strength of the acidic components, with the lower Ka value for HS- (1.3 × 10^-13) suggesting it is a weaker acid compared to H2S, but this does not negate the basic nature of the sulfide ion in solution.
