question 37

Multiple Choice

Solve the problem.
-The 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 $\mathrm { pH } = - \log x$ where $x$ represents the concentration of the hydrogen ions in the solution in moles per liter. Find the hydrogen ion concentration if the $\mathrm { pH } = 5$ .

• A) \(10 ^ { - 5 }\)
• B) 105
• C) \(1.61\)
• D) \(0.2\)
