Answer:
pH = 1.3
Explanation:
pH is used to measure the concentration of hydrogen ions in a solution. It can be calculated as follows:
pH = -log [H+]
Since the given solution is an acid, therefore, the concentration of H+ ions is the same as the molarity/concentration of the solution.
[H+] = 0.05 m
Substitute in the above equation to get the pH as follows:
pH = -log [H+] = -log [0.05] = 1.3
Hope this helps :)
