Answer:

$\huge{ \boxed{ \boxed{2.01}}}$

Step-by-step explanation:

pH is defined as the negative logarithm of the hydrogen ion concentration of a solution. That is,

$\bold{pH = -log([{H}^(+)])}$

From the question

$[{H}^(+)]$ = 9.7 × 10-³ M

We have,

$pH = - log(9.7 * {10}^( - 3) ) \\ = 2.01$

We have the final answer as,
