WebAnswer (1 of 2): A buffer is a mixture of a weak acid and its conjugate base. H2S is a weak acid H2S <=> H+ + HS- Sodium sulfide reacts with water to make Na+, HS- and OH-. That’s because there is no sulfide ion in solution. It hydrolyzes (reacts with water) to make HS- and OH-. Na2S(s) + HOH →... WebIntroducing: A free micro-site by Buffer.
