What is the pH of a solution within a solution with pH = 4.50? [H + ] = 3.25*10-6 M?

Answer: 5.48

Explanation:

pH is the negative logarithm of hydrogen ion concentration in a solution.

Mathematically, pH = - log (H+)

where H + represent the concentration of hydrogen ion

So, to get the pH of the solution with [H + ] = 3.25*10-6 M:

Apply, pH = - log (H+)

pH = - log (3.25*10-6 M)

pH = - (-5.48)

(Note that the minus signs will cancel out each other)

Therefore pH = 5.48

Now we know that the pH of the solution with hydrogen ion concentration of 3.25*10-6 M is 5.48 (i. e slightly acidic)

Thus, we can finally say 5.48 is the pH of the solution within a solution with pH = 4.50
