Question

Statement-1 : Stannous chloride is a powerful oxidising agent
which oxidises mercuric chloride to mercury.
Statement-2 : Stannous chloride gives grey precipitate with
mercuric chloride, but stannic chloride does not do so.

Answer 1

Answer:

Statement 1 is correct but statement 2 is incorrect

Answer 2

Both statement-1 and statement-2 are incorrect.

Explanation:

• Stannous chloride is tin(II) chloride. Its chemical formula is SnCl₂.
• It is a good reducing agent used in electrolytic baths but not a oxidising agent.
• When stannous chloride reacts with mercuric chloride, it reduced mercuric chloride to mercury. Stannous chloride cannot be reduced to mercuric chloride.
• $S n C l_{2}+H g C l_{2} \rightarrow S n C l_{4}+H g \downarrow$
• Stannic chloride is tin(IV) chloride. Its chemical formula is SnCl₄.
