Question

75.4 g of Na2S, sodium sulphide is mixed with water to form 4.0 L of solution. What is the concentration of the sulphide ions, S-2 in the solution? Hint: write out dissociation reaction

Explain what are the steps to be successful on these types of question and also the final answer of this question

Answer 1

in aqueous solution to form NaHS or Sodium Sulfide The reaction ... P4S10 (s) + 8R- OH (l) → 4 (R-O) 2 (PS) -SH (l) + H2S (g). NaOH (aq) + ... solutions where it will finally dissociate in sulfur ions.
