Re: Kw
Yes, in pure water the concentrations of hydronium and hydroxide are equal. When an acid or base is added though, these concentrations can change.

Re: Kw
Kw=[H3O+][OH-]
Kw= constant 1.0x10^-14
In neutral water with pH=7, the H3O+ and OH- concentrations are equal so
1.0x10^-14=[H3O+][OH-] with both of them being 1.0 x 10^-7.
