- B \(\mathrm{HgCO}_{3}, \mathrm{Hg}(\mathrm{OH})_{2}\)
- C \(\mathrm{Hg}(\mathrm{OH})_{2}\)
- D \(\mathrm{HgCO}_{3}, \mathrm{HgO}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{HgCO}_{3}, \mathrm{HgO}\)
Step-by-step Solution
Detailed explanation
The main product obtained when sodium carbonate reacts with mercuric chloride is mercuric oxide. \(\mathrm{HgCl}_{2}+\mathrm{Na}_{2} \mathrm{CO}_{3} \longrightarrow \mathrm{HgO}+\mathrm{CO}_{2}+2 \mathrm{NaCl} or \mathrm{HgCO}_{3}+2 \mathrm{NaCl}\)
