Laboratory Preparation of CO2 — Chemistry Keypoint

Laboratory Preparation of CO2

it is prepared in the laboratory by the action of mineral acid on trioxocarbonates.

lab preparation of CO2

CaCO3(S) + 2HCL(ag)    →.  CaCL2(ag) + H2O(L) + CO2(g)

Carbon (iv) oxide can also be obtained by heating of metallic tricocarbonates (except those of potassium and sodium),

Industrially, carbon (iv) oxide is obtained as a by-product in fermentation processes and when limestone is heated to make quick lime
