Choose the strongest acid. acid a, ka = 2.3 x 10-8 acid b, ka = 2.5 x 10-6 acid c, ka = 8.3 x 10-7 acid d, ka = 1.4 x 10-7

The strength of an acid can be predicted from its acid dissociation constant.

For a hypothetical monoprotic acid HA, the dissociation equilibrium is:

HA ↔ H+ + A-

Ka = [H+][A-]/[HA]

Now, higher the Ka value, greater is the dissociation and stronger is the acid strength

Based on the given examples, Ka is the highest for Acid B= 2.5 * 10⁻⁶. Hence Acid B is the strongest acid.

Ans: Acid B
