The higher the hydronium ion concentration of a solution, the ______ its pH.<br><br> higher or lower
andrey2020 [161]
<h3>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.
  • pH =-log[H+] =-log[H₃O+]
  • 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.
