Question

What is the ph of a 0.034 m hydrochloric acid solution?

Answer 1

PH= -log [H+]   
= - (log 0.034)   
= - (-1.5)   
= 1.5

Answer 2

Answer: The pH of the given HCl solution is 1.47

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
