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

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 The $\mathrm { pH }$ of a solution is given by $\mathrm { pH } = - \log x$ where $x$ represents the concentration of the hydrogen ions in th solution in moles per liter. Find the $\mathrm { pH }$ if the hydrogen ion concentration is $1 \times 10 ^ { - 2 }$ .

A) $- 12$
B) 2
C) $- 2$
D) 12
