Five solutions A, B, C, D and E

Five solutions A, B, C, D and E when tested with universal indicator showed
pH as 4, 1, 11, 7 and 9 respectively, classify the solutions as given below.
a) Neutral b) Strongly alkaline
c) Strongly acidic d) Weakly acidic e) Weakly alkaline
Arrange the pH increasing order of hydrogen ion concentration.

a) Neutral = D b) Strongly alkaline = C
c) Strongly acidic = B d) Weakly acidic = A
e) Weakly alkaline = E Increasing order :
Strongly alkaline < Weakly alkaline < Neutral < Weakly acidic < Strongly acidic
