DETERMINATION OF A CHEMICAL FORMUL 4. If some of the calcium metal remains unreacted when you start the titration, the calcium will react with hydrochloric acid to produce hydrogen gas. CaloH)₂ + 2HCl cacla & H2O Ca (s) + 2 HCl(aq) +CaCl2 (aq) + H2 (8) Would this cause error in the titration? If so, would more or less HCl be required? How would this affect the molecular formula for calcium hydroxide? bicarbonate that must be used to neutralize the...
