PPT-Electrolysis

Electrolysis Process by which an electric current is passed through a substance to cause a chemical change The chemical change is one in which the substance loses or gains an electron Electrolysis. 7. understand that the . first . process for manufacturing alkali from salt and limestone using coal . as . a fuel caused pollution by releasing large volumes of an acid gas (hydrogen chloride) . and creating .
