What happens to lime water inside an inverted test tube when the gas evolved passed through the delivery tube?
Why is this possible? Here is the setup: An inverted tube half filled with lime water is connected with a delivery tube to a hard glass test tube with calcium carbonate being heated.
Decomposition: CaCO3 --> CaO + CO2
Formation of milky precipitate in tube: CO2 + Ca(OH)2 --> CaCO3 (insoluble)
