a.No, solid nickel (II) hydroxide is soluble in water.

b.No, solid sodium sulfate is soluble in water.

c.Yes, solid nickel (II) hydroxide will precipitate out of the solution.

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.
