If, however, the carbide contains calcium chloride, frothing is liable to occur.
2
When its solution is boiled the substance breaks down into calcium chloride and chlorate:
3
The mineral apatite is composed of calcium phosphate, associated with calcium chloride, or fluoride.

Thus calcium chloride and sulphate are removed, and calcium sulphide, if present, is destroyed.

Also solid potassium carbonate may be used instead of calcium chloride for drying the gas.
