Question

what term is best described as the logarithmic measure of the concentration of hydronium ions in a solution

Answer 1

pH

Step-by-step explanation:

We define the pH of a solution as the negative logarithm of hydronium ions concentration in solution.

Thus when we want to define pH mathematically, we write;

pH = - log {H3O^+]

Where;

{H3O^+] means the concentration of hydronium ions in solution.
