Answer 2

Given:

the pH of a solution is 2.73.

To find:

The concentration of hydrogen ions.

Solution:

To determine the concentration of the hydrogen ion we have to follow the below formula as follows-

The pH of a solution is determined by-

$pH=-log[H^+]$.

The given pH is 2.73.

Let the concentration of the hydrogen ion is x.

So, we can write-

$2.73 = - log(x) \\ - 2.73 = log(x) \\ x = {10}^{ - 2.73} \\ x = 0.0018$

The concentration of the hydrogen ion is 0.0018M.
