Question

Explain why dilute trioxosulphate vi acid is not used to prepare carbon 4 oxide from calcium

trioxocarbonate 4​

Answer 1

H2SO4 cannot be used with CaCO3 to produce CO2 gas

Step-by-step explanation:

Because it does not dissolve in water- it forms a barrier on the surface of the unreacted CaCO3 which prevents any further reaction. A small volume CO2 is produced, this stops in short time.

I hope this helps :)
