Question
The pH of 0. 1 M solution of the following salts increases in the order :
Options
A.NaCl < NH4Cl < NaCN < HCl
B.HCl < NH4Cl < NaCl < NaCN
C.NaCN < NH4Cl < NaCl < HCl
D.HCl < NaCl < NaCN < NH4Cl
Solution
HCl is strong acid and hence pH of its 0.1 M solution will be least among the given solutions.
NH4 Clgiven acidic solution on hydrolysis, so its pH will be next to HCl.
NaCl does not hydrolyse and so gives neutral solution, so its 0.1 M solution will have pH greater than HCl and NH4
NaCN on hydrolysis gives alkaline solution and so its pH will be maximum.
NH4 Clgiven acidic solution on hydrolysis, so its pH will be next to HCl.
NaCl does not hydrolyse and so gives neutral solution, so its 0.1 M solution will have pH greater than HCl and NH4
