When a hydronium ion concentration equals 1 × $10 ^ { - 4 }$ moles per liter,what is the pH of the solution? Is the solution acidic or basic?

Question

Quizplus · Accepted Answer

The pH is calculated as the negative logarithm (base 10) of the hydronium ion concentration. For a concentration of $1 \times 10^{-4}$ moles per liter, the pH is -log(1 × $10^{-4}$) = 4. Since pH less than 7 is considered acidic, the solution is acidic.
