You could work out each one? right?
how the hell are you supposed to work it out. that's what we need to know

DrBob222 please answer only if you have a legitimate answer and explanation. This doesn't help me at all.

The answer is 0.1 M NaCl, Kb of about zero.
Kb is the amount of base and if there is no base (which translates to pOH=0) then it is extremely acidic (the pH=14).
I hope the explanation makes sense, but the answer is correct.
