Answer this correctly, only sincere answers please. I really need help. I will do all I can to make someone answer this. Thanks!
Marrrta [24]

Answer:

See Explanation

Explanation:

Let us recall that;

[H^+] [OH^-] = 1 * 10^-14

Where;

[OH^-] = 1 x 10^-11

Then;

[H^+] = 1 * 10^-14/1 x 10^-11

[H^+] = 1 * 10^-3

pH = -log [H^+]

pH = -log(1 * 10^-3)

pH = 3

Also;

pH + pOH = 14

pOH = 14 - pH

pOH = 14 -3

pOH = 11
