Question

Calcium carbonate is white is insoluble solid occurring naturally as chalk, limestone, marble and calcite.It is a useful building material. Divise a way of making some calcium carbonate from substance provided. Obtain it as powder
A). Method
B).Write balanced equation for the reaction used
D).Net ionic equation
E)Observation

Answer 1

A). Method: React vinegar (acetic acid) with calcium carbonate (in the form of limestone, chalk or marble) to produce calcium acetate, water, and carbon dioxide gas. Collect the gas and allow the mixture to dry, resulting in powdered calcium carbonate.

B). Balanced equation: CaCO3 + 2CH3COOH → Ca(CH3COO)2 + H2O + CO2

D). Net ionic equation: CaCO3 + 2H+ → Ca2+ + CO2 + H2O

E). Observation: Effervescence (bubbling) of carbon dioxide gas, formation of calcium acetate solution, and the production of a white powder (calcium carbonate) upon drying.
