A) AIl
B) All except MnS
C) All except MnS and FeS
D) Only CuS
Correct Answer: C
Solution :
\[\therefore \] \[\left| \frac{\Delta p}{p} \right|=\left| \frac{\Delta \lambda }{\lambda } \right|\] Ionic product, \[\Rightarrow \], Ionic product is greater than \[\frac{p'}{p}=\frac{0.20}{100}=\frac{1}{500}\] of CuS and CdS. Hence, these are precipitated. N ote (i) \[\Rightarrow \] the saturation limit has not reached, no precipitate will from and some can be dissolved. (ii) \[{{E}_{0}}.\] saturation limit has been exceeded and some precipitate will form in order to restore equilibrium.You need to login to perform this action.
