How many mL of 0.655 M phosphoric acid solution are required to neutralize 15 mL of 1.284 M #NaOH# solution?
Well, you need to know that phosphoric acid is a DIACID in aqueous solution... The third proton is rarely removed.
And we write the stoichiometric equation as...
And so .................
And so we take the quotient....
Reaction will be -
Moles required to neutralize
Let the volume required to neutralize
