The pH of a solution is a measure of the hydronium ion concentration. The hydronium ion is represented as . Mathematically, the relationship between hydronium ion concentration and pH can be written as:
This equation can be further written as:
In this case, pH = 4.66.
Therefore, the hydronium ion concentration can be calculated by substituting the value of pH in the above equation.
That is,
Thus, the given solution contains 2.19 x 10^-5 M hydronium ions.
We can also calculate the pOH of the solution by using the relation:
pH + pOH = 14
This equates to: pOH = 14-4.66 = 9.34
We can also calculate [OH^-] by using the relation:
Solving this equation, we get [OH^-] = 4.57 x 10^-10 M.
Hope this helps.
