the answer to the question is d..........

d. Yes, a solid sodium sulfate will precipitate out of the solution.

Let's write the balanced chemical equation for the reaction:

NiSO₄(aq) + 2NaOH(aq) → Na₂SO₄+ Ni(OH)₂

This reaction is a double replacement reaction.

  • A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products.
  • Usually, a double displacement reaction results in precipitate formation.
  • It can also be known as double replacement reaction.

In this reaction, a precipitate of sodium sulphate is formed out with the presence of nickel hydroxide.
