JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
The volume (in \(mL\) ) of \(0.1\,M\,AgNO _3\) required for complete precipitation of chloride ions present in \(20\,mL\) of \(0.01\,M\) solution of \(\left[ Cr \left( H _2 O \right)_5 Cl \right] Cl _2\) as silver chloride is \(..........\).
- A \(4\)
- B \(3\)
- C \(2\)
- D \(1\)
Answer & Solution
Correct Answer
(A) \(4\)
Step-by-step Solution
Detailed explanation
\(\left[ Cr \left( H _2 O \right)_5 Cl \right] Cl _2+2 AgNO _3 \rightarrow\) \(\begin{array}{ll}0.01\,M , 20\, mL & 0.1\, M \\ \text { For } 0.2 \text { milimole } & AgNO _3 \text { required }\end{array}\) \(0.4=0.1 \times V ( ml )\) \(V =4\,mL\)
