Question

A container of orange juice has a pH of 3.3. Find the concentration of hydronium ions in the milk.

Answer 1

The concentration of the hydronium ions in the milk is 5.011×10⁻⁴ if  the container of orange juice has a pH of 3.3.

What is pH value?

The pH of a solution is a measurement of the concentration of hydrogen ions in the solution, as well as its acidity or alkalinity. Normally, the pH scale ranges from 0 to 14.

We have:

A container of orange juice has a pH of 3.3.

The pH value = 3.3

$\rm pH = -log[H_3O^+]$

$\rm 3.3 = -log[H_3O^+]$

Removing log:

$\rm 10^{-3.3}=[H_3O^+]$

$\rm [H_3O^+] = 5.011\times10^{-4}$

Thus, the concentration of the hydronium ions in the milk is 5.011×10⁻⁴ if  the container of orange juice has a pH of 3.3.
