Answer 1

In this question, we have to determine the value of [H+] from a given value of pOH, 8.27.

In order to do that, we need to find the pH value using the pOH value, this is because pH and pOH have a mathematical relationship:

pH + pOH = 14

pH + 8.27 = 14

pH = 14 - 8.27

pH = 5.73

Now that we have the pH value, we can find the value of [H+] using the following formula:

[H+] = 10^-pH

[H+] = 10^-5.73

[H+] = 1.86*10^-6 M
