Calculate the pH of a 0.01 molar aqueous solution of strong monoprotic hydrochloric acid, assuming complete dissociation.
A. 1
B. 2✓ Correct Answer
C. 3
D. 4
💡 Solution & Explanation
The pH of a solution is defined as the negative logarithm to the base 10 of the hydrogen ion concentration expressed in moles per liter. For a 0.01 molar or 10 to the power minus 2 molar solution of strong hydrochloric acid, the hydrogen ion concentration equals 0.01, yielding a pH of 2. Strong acids dissociate entirely in aqueous solution.
