Solve the Problem $\mathrm { pH }$ Of a Solution Ranges from 0 to 14

question 16

Multiple Choice

Solve the problem.
-The $\mathrm { pH }$ of a solution ranges from 0 to 14 . An acid has a pH less than 7 . Pure water is neutral and has a pH of 7 . The $\mathrm { pH }$ of a solution is given by $\mathrm { pH } = - \log \mathrm { x }$ where $\mathrm { x }$ represents the concentration of the hydrogen ions in the solution in moles per liter. Find the hydrogen ion concentration if the $\mathrm { pH } = 8.4$ .

• A) \(3.98 \times 10 ^ { - 9 }\)
• B) \(3.98 \times 10^{ - 8}\)
• C) \(2.51 \times 10 ^ { - 8 }\)
• D) \(2.51 \times 10 ^ { - 9 }\)
