The concentration of the hydronium ion in hydrochloric acid is 0.0045 M, and the pH of the solution is 2.34.
<h3>What is pH?</h3>pH is the potential of the hydrogen or the hydronium ions in the aqueous solution.
As the solution contains HCl the concentration of the hydronium ion will be the same,
The pH of the solution is calculated as:
The concentration of the hydroxide ion is calculated from pH and hydronium ion as:
Now, for the calcium hydroxide solution, the calculations are shown as,
pOH is calculated as:
The concentration of calcium hydroxide is calculated as:
Therefore, the pH and the pOH give the concentration of the hydrogen or the hydronium ion and the hydroxide ion.
