The little dipper is located in Ursa Minor you would also get a clue because... Minor and little
A. Variables, this is because you can choose what you're testing
Because ok the change that mayde
When the solution is pure water so,
Kw = [OH-][H3O+]
when [OH-] = [H3O+] we can assume both = X
and Kw = 1.47 x 10^-14
by substitution:
1.47 x 10^-14 = X^2
∴ X = √(1.47 x 10^-14)
= 1.2 x 10^-7 M
