Question
I need help with a gen chem lab. I mixed CaCO3 (calcium carbonate) and HCl (hydrochloride) together and had to record what happened. When the two chemicals were combined, the reaction was that is it fizzed. I need help filling in the information. If you can give complete details of how you got the answer, that would be GREAT!!
Reactants in A
Name Molecular Formula Best Representation of compound in aq solution
Calcium Carbonate CaCO3 ?
Hydrochlorate HCl ?
Evidence of any Reaction: Fizzed
Molecular Equation: ?
Products in A (if any)
Name Molecular Formula Best Representation of compound in aq medium
? ? ?
? ? ?
(total) Ionic equation: ?
Net Ionic equation: ?
Explanation / Answer
molecular equation =
CaCO3 + 2HCl ----> CaCl2 + H2O + CO2...............CO2 is what fizzed
Products formed are
Calcium Chloride CaCl2
Carbon di oxide CO2
total ionic =
Ca2+ + CO3^2- + 2H+ + 2Cl- ----> Ca2+ + 2Cl- + H2O + CO2
net ionic =
2H+(aq) + CO3-2(aq) --> H2O(l) + CO2(g)
