Respuesta :

In this question, we have to find the H+ concentration from the given pH, and we need to do the opposite calculation of the pH formula, since the formula is:

pH = - log [H+]

To find the ion concentration we have the formula:

[H+] = 10^-pH

Adding the 4.9 value into this formula, we will have:

[H+] = 10^-4.9

[H+] = 1.3*10^-5
