The kw of water varies with temperature. calculate the ph of water at 46⁰c with a kw = 1.219 x 10-14. show all calculations leading to an answer.

Kw = 1.219x10⁻¹⁴

kw = [H⁺] x [OH⁻]

in water [H⁺] = [OH⁻] therefore:

[H⁺] = √ kw

[H⁺] = √ 1.219x10⁻¹⁴

[H⁺] = 1.104x10⁻⁷

pH = - log [H⁺]

pH = - log [ 1.104x10⁻⁷ ]

pH = 6.95

hope this helps!

It dont even matter because at the end of thre day we gone life like it ius s

Well you can immediately rule out a and d because if a metal were to lose or gain protons, then it would become a different element all together. the answer here is b because the positive symbol with a number refers to how many electrons the metal can give away to become stable.
