Answer:</h3>
The higher the hydronium ion concentration of a solution, the <u>lower</u> its pH.
<h3>
Explanation:</h3>
- The pH is the measure of acidity or alkalinity of a substance.
- We calculate pH by using;
pH = -log[H+]
- The lower the pH of a solution the more acidic it is and the higher the pH the more basic or alkaline it is.
- From this relationship, the higher the hydronium ions concentration of a solution the lower the pH and the more acidic a solution is.
For example,
Solution A with a [H₃O+] of 0.003 M will have a pH of
pH = -log 0.003 M
= 2.52
While, a solution B with a [H₃O+] of 0.025 M will have a pH of
pH = -log 0.25 M
= 1.60
Therefore, the higher the concentration of hydronium ion of a solution the lower its pH is.
