back titration
« on: November 24, 2009, 06:14:15 PM »
when an indigestion tablet containing CaCO3 is added to HCl...the reaction produces CO2 which escapes so then what is left in the beaker?H20 CaCL2(salt) and unreacted HCl ? so 3 things remain?

Yes. Although I would rather think in terms of ions present - Ca2+, H+, Cl-.

That is, assuming there was excess of HCl, not excess of carbonate ;)
