Question #33032
what chemical should you add to make these solid? calcium carbonate + water + what chemical? Thankyou
Expert's answer
calciumcarbonate + water + what chemical
This chemical- H2SO4

H2SO4 + CaCO3 --> CaSO4(s) + H2O + CO2, so:

CaCO3 + H2SO4 + H2O => CaSO4 + (CaOH)2SO4 + CO2

Generally, when yousee a carbonate group in the reactants part of a reaction, the products will contain CO2 in it.

CaCO3 is highly insoluble in water and will not usually dissolve in any significant amount in water unless CO2 is present and dissolved in the water. This is the only possible reaction and it is highly unlikely to happen at all, in fact the reverse reaction is much more favored.

CaCO3(s) + H2O(l) → Ca(OH)2(s) + CO2(g)
