Explanation / Answer

Active ingredient             BaCl2(aq) added

1) CaCO3              white precipitate of BaCO3, CaCO3(white solid) +BaCl2(aq)---->BaCO3(s) +CaCl2(aq)

2) cornstarch                No reaction

3) Na2B4O9.H2O           no reaction

4) NaCl                        no rxn

5) ascorbic acid           no rxn

6) sucrose                   no rxn

Active ingredient             HCl added

1) CaCO3                        CO2 released ,CaCO3aq) +HCl(aq) --->CO2(g) + H2O(l)      

2) cornstarch                No reaction

3) Na2B4O9.H2O           no reaction
