D

is neutral, as its

p H

value is equal to 7

C

is strongly alkaline, as its

p H

value is 11.

B

is strongly acidic, as its

p H

value is equal to 1

A

is weakly acidic, as its

p H

value is equal to 4 and more than solution

B

E

is weakly alkaline, as its

p H

value is equal to 9 and less than

C

p H

value of the given solution in increasing order of hydrogen-ion concentration:
