Question

Any tips on how to go about solving almost any acid base equilibirum problem (1st year university chemistry)

Answer 1

Water and a salt are always formed. Thats the only tip I can think of.

Answer 2

You should know that you will always need a completely balanced chemical equation.
That when you are doing problems with a base reaction, always include H2O in the equation.

If it is strong-weak reactions, the weak will always be fully neutralized for a strong conjugate. (Thats where you'll need things like your K value and all that crap)

If it is strong- strong reactions, you will not need to find equilibrium. Its more common sense. If the amounts are equal, its neutral. If one is in excess, you know which way equilibrium will shift.
