Question

Sort the following substances with their mentioned pH values in increasing order of acidic nature.

• A. $H_{2}S{O}_4$ (2.75)
• B. Drinking Water (6.2)
• C. $HCl$ (3.01)
• D. Carbonic acid (4.68)
• E. Citric acid (3.24)

Answer 1

Lower the pH, higher the acidic character. Hence, the increasing order of acidic nature of the given substances is:
Drinking water (6.2) < Carbonic acid (4.68) < Citric acid (3.24) < HCl (3.01) < $H_{2}S{O}_4\left(2.75\right)$
