What type of following solution is obtained from amalgam of mercury with sodium?

A Liquid in solid
B solid in gas
C solid in solid
D solid in liquid

Verified Solution

Answer & Solution

Correct Answer

(A) Liquid in solid

Step-by-step Solution

Detailed explanation

\(
\begin{aligned}
& \text {Mercury} \rightarrow \text {liquid} \\
& \text {Sodium} \rightarrow \text {Solid}
\end{aligned}
\)
Amalgam of mercury with sodium is an example of solid solutions. It contains a liquid solute and solid solvent.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
