# Calculate the pH of a {eq}4.25 \times 10^{-4} {/eq} M HCl solution.

## Question:

Calculate the pH of a {eq}4.25 \times 10^{-4} {/eq} M HCl solution.

## Strong Acid:

An Arrhenius acid reversibly dissociates some number of its available covalent "H-X" bonds in an aqueous solution to create hydrogen ion and conjugate base products. If the reaction begins with the acid and pure water, then an acidic solution is created with a pH below 7. If the acid is relatively strong, then this reaction proceeds to completion and the remaining acid molarity at equilibrium is negligible. The hydrogen ion product molarity has a simple stoichiometric relation to the starting acid molarity.

Hydrochloric acid (HCl) is a strong monoprotic Arrhenius acid. It will completely dissociate in aqueous solution to create the same hydrogen ion...
