i'm having trouble with titration calculations.
How would you attempt this problem?

50mL of a 0.50M H2SO4 is added to 100mL of 0.25M H2SO4. Calculate the final concentration of the acid.

Also: how would you show that aluminum sulphate would show acidic properties using balanced equation? Would it have something to do with Hydrolysis?

First questions: using stoichiometru find the total number of moles of H2SO4 present in each sample. Add that together and divide by the total volume...and voila.

Think about the sulfate ion in particular (hint: [tex]HSO4^{-1}[/tex] is a weak acid)
