The lowering in vapour pressure is maximum for
- A \(0.1 \mathrm{M}\) urea
- B \(0.1 \mathrm{M} \mathrm{NaCl}\)
- C \(0.1 \mathrm{M} \mathrm{MgCl}_{2}\)
- D 0.1 \(\mathrm{M} \mathrm{K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]\)
Answer & Solution
Correct Answer
(D) 0.1 \(\mathrm{M} \mathrm{K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]\)
Step-by-step Solution
Detailed explanation
Lowering in vapour pressure is a colligative property so, the number of particle (i.e. ion) increase, which results in decrease of vapour pressure. The lowering in vapour pressure is maximum for \(0.1 \mathrm{M} \mathrm{K}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]\), as it…
