Under which set of conditions is the ionic product of water, Kw, constant at a given temperature in aqueous systems?
- in dilute acidic but not dilute alkaline solutions.
- in dilute alkaline but not dilute acidic solutions.
- in both dilute acidic and alkaline solutions.
- only at the equivalence point of a strong acid-strong alkali titration.
- only in pure water.
The Attempt at a Solution
I don't understand what this question is asking. Is it asking in which scenario is the Kw constant for all temperatures or does it never change? Both of these I don't understand, could someone explain this to me?
