### Kw = (Ka)(Kb)

If only Ka or Kb is given and the temperature is not stated, can we assume that it is at 25 Celsius and use 1.0x10^-14 to find the constant we need?

Yes, if no temperature is stated you can assume 25 Celsius to solve!

Yes, you can assume that the temperature is 25 degrees and you can use the equation.

What would happen if a temperature is given? Would I not be allowed to use the equation?

Correct! 25 degree Celsius is the right temperature to assume.
