Precipitation of II group cations takes place when H 2 S gas passed is : (in presence of dilute HCl)
Text Solution
Verified by ExpertsThe correct answer is:
C
H 2 S 
2H + + S 2– ; H 2 S 
2H + + S 2–
On account of common ion effect the ionization of H 2 S is suppressed Ksp of 2nd group sulphides are lower, so, only those basic radicals get precipitated.
