Give examples of chemical reactions that can be used to prove the basic nature of a calcium compound (oxide and hydroxide). What reaction can be used to detect calcium ions in solution? Write the equation of a chemical reaction in molecular, complete and abbreviated ionic form.

Explanation of the solution to the problem: in order to prove the basic nature of calcium compounds, it is enough to give equations with acid oxide and acid, because only compounds with basic properties can react with acid compounds.
CaO + CO2 => CaCO3;
Ca (OH) 2 + H2SO4 => CaSO4 + 2H2O.
A qualitative reaction to calcium ions Ca ^ (2+) is an interaction with carbonates with the formation of a water-insoluble white precipitate of calcium carbonate:
CaCl2 + Na2CO3 => 2NaCl + CaCO3;
Ca ^ (2+) + 2Cl ^ (-) + 2Na ^ (+) + CO3 ^ (2-) => 2Na ^ (+) + 2Cl ^ (-) + CaCO3;
Ca ^ (2+) + CO3 ^ (2-) => CaCO3.
