Explanation / Answer

ANS.) 1. given Mcanberry = 3.47 x 10-3

Vcanberry = 1ml

no.of moles of H+ ions = M x V

= 3.47 x 10-3 x1 = 3.47 x 10-3 gmoles

no.of moles of OH- ions = 0.1 x0.94 = 0.094 gmoles

no.of H+ ions left after titration = 0 ( since [OH-] .> [ H+] )

total acid content = 0 after titration
