Answer: The pH of the given HCl solution is 1.47

Step-by-step explanation:

We are given:

Molarity of HCl = 0.034 M

1 mole of HCl produces 1 mole of hydrogen ions and 1 mole of chlorine ions.

pH is defined as negative logarithm of hydrogen ion concentration. It is basically defined as the power of hydrogen ions in a solution.

Mathematically,

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

We are given:

[H^+]=0.034M

Putting values in above equation, we get:

$pH=-\log(0.034)\\\\pH=1.47$

Hence, the pH of the given HCl solution is 1.47
