JEE Main 2020Ionic Equilibrium Question with Solution

JEE Main 2020 (06 Sep Shift 1)

Question

Arrange the following solutions in the decreasing order of pOH :
(A) 0.01 MHCl
(B) 0.01 MNaOH
(C) 0.01 MCH3COONa
(D) 0.01 MNaCl

Choose an option

Show full solutionCorrect option: B
Correct answer
B(A)>(D)>(C)>(B)

Step-by-step explanation

   pH 0.01MHCl=2
pH of 0.01MNaOH=12
pH of 0.01MCH3COONa>7
pH of 0.01MNaCl=7
So the order of pH:B>C>D>A

So the order of pOH:  B<C<D<A
