3 - Making Carbon Dioxide - IGCSE Chemistry
Calcium Carbonate + Hydrochloric Acid --> Calcium Chloride + Water + Carbon Dioxide. You would see the Calcium Carbonate slowly dissolve and the Carbon Dioxide being made as bubbles. But you would not see the Calcium Chloride or the water being made since there is already water in the flask and the C al cium Chloride will dissolve in it.
Calcium chloride - Simple English Wikipedia, the free …
Calcium chloride is a chemical compound made of calcium and chlorine atoms. It has the formula of CaCl 2.It absorbs water from the air and releases heat when it is dissolved in water. It is used as a de-icer on roads to melt the ice. It can be formed by mixture of calcium oxide with hydrochloric acid, but this produces a version that is hydrated (has water molecules attached to it).
