Calcium Chloride and Hydrochloric Acid

Because it has a better quality

Because it's cheaper than other carbonates

Because it cheap and easily available

Because other carbonates do not react with HCl

CaCO3 + 2HCl -> CaCl2 + CO2 + H2O

CaCO2 + 2HCl -> CaCl3 + H2O + HCl

CaCO3 + HCl -> CO2 + 2H2O + CaCl2

Lime water turns dark

Brown Fumes Are Released

Splinter Ignites

Ignited Splinter Extinguishes

It will produce Sulphur Dioxide

It will react too violently

It will not react

It will stop the reaction
