HCl is limiting reagent don't forget to add the volumes

but mmol of both are same !!!!so then ph=7 ???

I know i am going in wrong direction........plzzzz help

you should think about mili equivalent not of mili moles

yeah eureka, 1 mole of HCl gives 1 mole of H+

but 1 mole of Ba(OH)2 gives 2 moles of OH-.

ok i got it........thanx everyone.......
