unit 2 chemistry question

If 250 ml of 0.5M HCL is added to 300ml of 0.2M KOH solution, what is the pH of the final solution.

I know how to work out pH, but not pH of two solutions mixed together

I'll give you a hint - when you add the two solutions together, the following reaction will occur:

H+ (aq) + OH- (aq) ----> H2O (l)

Think limiting reagent.
