Question

Преобразование нерастворимого карбонат кальция в расстворе кальций гидрокарбанат во время дейсвия остатка CO2 напишите пожалуйста формулу

Answer 1

CaCO₃ + CO₂ + H₂O = Ca(HCO₃)₂

Answer 2

Conversion of Insoluble Calcium Carbonate to Soluble Calcium Hydrogencarbonate

When carbon dioxide (CO2) is added to water containing insoluble calcium carbonate (CaCO3), it reacts to form soluble calcium hydrogencarbonate (Ca(HCO3)2). This reaction is commonly observed in natural processes such as the dissolution of limestone or the formation of stalactites and stalagmites in caves.

The chemical equation for this reaction can be represented as follows:

CaCO3 + CO2 + H2O → Ca(HCO3)2

In this reaction, carbon dioxide dissolves in water to form carbonic acid (H2CO3), which then reacts with calcium carbonate to produce calcium hydrogencarbonate. The resulting calcium hydrogencarbonate is soluble in water, allowing it to remain in solution.

It is important to note that the reaction between carbon dioxide and calcium carbonate is reversible. When the concentration of carbon dioxide decreases or the pH of the solution increases, the reaction can proceed in the opposite direction, resulting in the precipitation of calcium carbonate.
