Excess of silver nitrate solution is added to \(100 \mathrm{~mL}\) of \(0.01 \mathrm{M}\) pentaaqua chloro chromium (III) chloride solution. The mass of silver chloride obtained in grams is [Atomic mass of silver is 108].
- A \(287 \times 10^{-3}\)
- B \(143.5 \times 10^{-3}\)
- C \(143.5 \times 10^{-2}\)
- D \(287 \times 10^{-2}\)
Answer & Solution
Correct Answer
(A) \(287 \times 10^{-3}\)
Step-by-step Solution
Detailed explanation
The reagent is \(\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{5} \mathrm{Cl}^{2} \mathrm{Cl}_{2}\right.\)
No. of moles of \(\mathrm{Cl}^{-}\)ion present
\[
\begin{aligned}
&=\frac{2 \times 100 \times 0.01}{1000} \\
&=0.002 \\
\therefore \quad \text { Mass of } \mathrm{AgCl} &=0.002 \times 143.5 \\
&=0.287 \\
&=287 \times 10^{3} \mathrm{~g}
\end{aligned}
