Thelma · Answer 1

The pH of the solution is 2.26

Explanation:

In this question, we are asked to calculate the pH of an acidic solution having a specific concentration of hydrogen ions.

Generally speaking, pH is the negative logarithm to base 10 of the concentration of hydrogen ions in a solution.

Mathematically:

pH = - log[H+]

According to the question, [H+] = 0.005496

pH = - log (0.005496)

pH = 2.26

Hence, the pH of a solution with hydrogen ion concentration of 0.005496 is 2.26. It can be interpreted that this solution is strongly acidic. This is because, the lower in value that they are on the pH scale, the more acidic they are
