« HOW TO MAKE CALIUM CARBONATE FROM SHELLS »

This method is based on base the extraction of carbonate from sea rock,it’s like the famous way of extraction by attaking the rock  with HCL acid clorydric then the reaction begin and shells become solution(slowly we add shells on the acid to disolve all the shells),it react to form calcium carbonate but the bubbles at the start are thick and very annoying .

The foam starts to ease up and you will be able to add it faster near the end.

Finally you filter the solution by filter paper on any other bucker,you should left with NACL (sel) in solution and CaCoO3 in the filter.

We can make products(poudre CaCoO3) and  NACL (sel) after evaporation as(produit derivé).
