Question

The pH of four solutions A,B,C and D are given below:

A = 1, B = 8.5, C = 13 and D = 5.

Arrange the solutions according to the increasing order of their acidity:

• A. A<B<C<D
• B. C<B<D<A
• C. B<A<C<D
• D. C<D<B<A

Answer 1

The correct option is B

C<B<D<A

As pH increases, the acidic nature decreases. So

the increasing order of acidity is : C<B<D<A
