The hydrogen ion concentration of a solution is 1 × 10^-4 M.What is the pH of the solution,and is it acidic or basic?

Question

Quizplus · Accepted Answer

The pH of a solution can be calculated as pH = -log([H+]). 
Using this formula and plugging in the given concentration of hydrogen ions, we get pH = -log(1x10^-4) = 4. 
Since the pH is less than 7, the solution is acidic. Therefore, the correct answer is E) pH = 4, acidic.
