My apologies,
My question refers to the carbonation of calcium. Specifically, when calcium carbonate is precipitated from a solution of calcium hydroxide as per :
Ca(OH)2 + CO2 → CaCO3 + H2O
All the preciptation reactions that I know of are metathesis but I'm not 100% sure about this one. Is it metathesis or is it something else? Any help would be most welcome.
