question 91

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 $\mathrm { pH }$ if the hydrogen ion concentration is $9.5 \times 10 - 10$ .

• A) \(9.02\)
• B) \(10.98\)
• C) \(10.02\)
• D) \(9.98\)
