Question

An HCl solution has a concentration of 3.26 x 10-2 M. What is the pH of this solution?

pH = 12.5

pH = 1.49

pH = 3.3

pH = 2.0

Answer 1

- log (3.26x10^-2) = 1.49 which is B

Answer 2

Answer: The pH of the solution is 1.49

Step-by-step explanation:

pH is defined as the negative logarithm of hydrogen ion concentration present in a solution.

To calculate the pH of the reaction, we use the equation:

`pH=-\log[H^+]`

where,

`[H^+]=3.26* 10^(-2)M`

Putting values in above equation, we get:

`pH=-\log(3.26* 10^(-2))\\\\pH=1.49`

Hence, the pH of the solution is 1.49
