Question

At hundred degree celsius kw is equal to 10 to the power

Answer 1

Answer:

Kw of water = [H+][OH-]

10-12 = [H+][OH-] at 100oC

Let us assume the concentration of H+ = x

Since each water molecules dissociates into one proton and one hydroxide ion.

i.e. the quantity or the concentration of these two ions will be equal in water.

[H+] = [OH-]

Therefore

10-12 = x.x

10-12 = x2

x = 10-6

[H+] = [OH-] = 10-6

pH = - log [H+] = - log 10-6 = 6 log 10 = 6
