JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
When \(35\, mL\) of \(0.15\, M\) lead nitrate solution is mixed with \(20 \,mL\) of \(0.12\, M\) chromic sulphate solution, ....... \(\times 10^{-5}\) moles of lead sulphate precipitate out. (Round off to the Nearest Integer).
- A \(565\)
- B \(525\)
- C \(235\)
- D \(412\)
Answer & Solution
Correct Answer
(B) \(525\)
Step-by-step Solution
Detailed explanation
\(3 Pb \left( NO _{3}\right)_{2}+ Cr _{2}\left( SO _{4}\right)_{3} \rightarrow \)\( 3 PbSO _{4}+2 Cr \left( NO _{3}\right)_{3}\) \(35\, ml \quad 20\, ml\) \(0.15\, M \quad 0.12\, M\) \(5.25\, m \cdot mol =2.4\, m \cdot mol \quad 5.25 \,m \cdot mol\)…
