Question

 The pH values of six solutions A to F are given below:

A = 0, B = 11, C = 6, D = 3, E = 13, F = 8

Which of the above solutions are (i) acids (ii) alkalis?

Answer 1

(i) Acidic solutions: A with pH = 0, D with pH = 3, C with pH = 6 
(ii) Basic solutions: F with pH = 8, B with pH = 11, E with pH = 13
