the purpose of adding hydrochloric acid in the experiment is to remove
Homework Answers
Barium carbonate react with hydrogen chloride to produce barium chloride, carbon dioxide and water. Chemical reaction.
Full Balanced equation:
BaCO3(s) + 2 HCl(aq) ===> BaCl2(aq) +
H2O(l) + CO2(g)
We can write the equation with only participating ions
2H+ + CO32- ==> H2O(l) + CO2(g)
