The solution contains salts: sodium chloride, potassium sulfate, calcium nitrate and magnesium sulfate.

The solution contains salts: sodium chloride, potassium sulfate, calcium nitrate and magnesium sulfate. Potassium carbonate was added to it. A white precipitate fell out. What is this sediment? Make up the equations of the ongoing reactions (in molecular and ionic forms).

Let’s make a chemical. reaction and write it in the form of an equation:

Ca (NO3) 2 + K2CO3 = CaCO3 ↓ + 2KNO3;
Ca (+2) + 2NO (3-) + 2K (+1) + CO3 (-2) = CaCO3 ↓ + 2K (+1) + 2NO3 – Ca (+2) + CO3 (-2) = CaCO3 ↓;

MgSO4 + K2CO3 = MgCO3 ↓ + K2SO4;
Mg (+2) + SO4 (-2) + 2K (+1) + CO3 (-2) = MgCO3 ↓ + 2K (+1) + SO4 – 2Mg (+2) + CO3 (-2) = MgCO3 ↓;

The white precipitate will be a mixture that does not dissolve in water in the form of CaCO3 and MgCO3 salts.
