Question

What is the pH of an HCL solution if [H+]=0.03​

Answer 1

pH = 1.5

Step-by-step explanation:

The pH is always equal to -log[H+].

Simply plug it into this formula to find the pH. In order to find the concentration from the pH, you can do:

`10^(-pH)` = [H+]

Answer 2

The answer for the following problem is mentioned below.

• Therefore the pH of an HCl solution is 1.52.

Step-by-step explanation:

pH:

It is a measure of the hydrogen ion concentration,a measure of acidity or the alkalinity of a solution.

(or)

The negative logarithmic function of the hydrogen ion concentration is called the pH.

The formula for the pH is as follows:

pH = -log [
`H^(+)`]

pH less than 7 indicates that solution is acidic

pH greater than 7 indicates that the solution is basic

Given:

hydrogen ion concentration [
`H^(+)`] = 0.03 = 3 ×
`10^(-2)`

To calculate:

pH of a solution

We know;

pH = -log [
`H^(+)`]

where,

`H^(+)` represents the hydrogen ion concentration

pH = -log [3×10^-2]

pH = 1.52

Therefore the pH of a solution is 1.52

Therefore the pH of an HCl solution is 1.52.
