Final answer:
Yes, a precipitate will form when a solution of Hg₂SO₄ is mixed with a solution of NaOH. Both Hg₂(OH)₂ and Na₂SO₄ will precipitate.
Step-by-step explanation:
A solution of Hg₂SO₄ and NaOH will form a precipitate. The answer is (d) yes: both Hg₂(OH)2 and Na₂SO₄ will precipitate. When Hg₂SO₄ (mercury(II) sulfate) reacts with NaOH (sodium hydroxide), the following chemical equation occurs:
Hg₂SO₄ (aq) + 2NaOH(aq) → Hg₂(OH)₂ (s) + Na₂SO₄ (aq)
The Hg₂(OH)₂ that is formed is insoluble and will precipitate from the solution, as well as the Na₂SO₄. Therefore, both precipitates will form in the reaction.
