It is the only way of dissolving CaCO3.
HCl + CaCO3 --> Ca2+ + H2O + CO2
In neutral water CaCO3 is insoluble.
The reaction between chalk (calcium carbonate, CaCO3) and hydrochloric acid (HCl) can be represented by the chemical equation: CaCO3 + 2HCl → CaCl2 + CO2 + H2O
eggshell is a kind of compound CaCO3 (calcium carbonate)
If the limestone rock fizzes when dilute acid is added, it indicates the presence of calcium carbonate in the rock. When calcium carbonate reacts with acid, it produces carbon dioxide gas, which causes the fizzing.
Calcium Carbonate is a compound and an element. However, it is not a mixture. If it is a compound or a element, then it can not be a mixture
Molar mass of CaCO3 = 66.1221g CaCO3/mole CaCO3. This means that 1 mole CaCO3 = 66.1221g CaCO3. To find the mass of 4.5 mole CaCO3, complete the following calculation: 4.5g CaCO3 X 1mol CaCO3/66.1221g CaCO3 = 0.068 mole CaCO3.
To test limestone for its calcium carbonate (CaCO3) content, you can use an acid test. By adding a few drops of dilute hydrochloric acid to a sample of limestone, a reaction will occur if it contains calcium carbonate, producing bubbles of carbon dioxide gas. The intensity of the reaction can indicate the purity of the limestone.
CaCO3 (calcium carbonate) is a mild base, and as such reacts to neutralise acids. Vinegar is a dilute solution of acetic acid (AcH). CaCO3 + 2AcH --> H2O + CO2 + CaAc
I have the same task. Maybe this one would work: If amount of CaCO3 is known I would try to add stechiometric amount of any diluted acid (e.g. HCl), which would form Ca water soluble salt to solution of MgCO3/CaCO3 in water (note, that these salts are not soluble in water, therefore that will colloid solution). The reaction would be CaCO3+2HCl=CaCl2+H2O+CO2. Calcium is more reactive metal than Mg, therefore, CaCO3 would react first if you add acid. After all CaCO3 is consumed, just filter of MgCO3

No such substance as 'CaCo2'. Do you mean calcium carbonate, in which case the formula is 'CaCO3'? or do you mean an alloy(mixture) of 1 part calcium(Ca) to 2 parts cobalt(Co)?

It is CaCO3.....it is the same as marbleFormula: CaCO3
caco3 is solid form. its density is high so caco3 is not soluble in water. but co2 mix in water befuor the mix in caco3 . so caco3 is soluble after mixing the co2 .
the answer is DECOMPOSITION... and that is the answer not CaCO3
