Q.The solubility product of $PbCl_2$ is $1.6 \times 10^{-5}$ . On mixing $300 \text{ mL}$ of $0.1 \text{ M } Pb(NO_3)_2$ and $100 \text{ mL}$ of $0.2 \text{ M } HCl$ , will precipitation occur?

Yes, because

Q_{sp} > K_{sp}

No, because

Q_{sp} < K_{sp}

No, because it forms a buffer

Yes, because it is a neutral salt

The correct solution involves applying the fundamental concept to derive the final value step by step...
