CaCl2 + Na2SO4 = CaSO4 + NaCl

Balanced Chemical Equation – Solution

CaCl2 + Na2SO4 → CaSO4 + 2NaCl

The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.

Chemical Reaction Information

This is a precipitation reaction: CaSO4 is the formed precipitate.

Calcium Chloride + Sodium Sulfate = Anhydrite + Sodium Chloride

Reaction Type

Double Displacement (Metathesis)

Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
