A 001 M Solution of a Substance Has a PH of of 2

Question

A 0.01 M solution of a substance has a pH of 2. What can you conclude about this substance?
A) It is a strong acid that ionizes completely in water.
B) It is a strong base that ionizes completely in water.
C) It is a weak acid.
D) It is a weak base.
E) It is neither an acid nor a base.

Accepted Answer

A pH of 2 indicates a highly acidic solution. A 0.01 M solution of a strong acid would ionize completely in water, leading to a high concentration of H+ ions, which corresponds to the low pH value.
