iONIC EQUATION:
2Na2+ +SO42-+2Cl-+ Ca2+---------- Ca2+ + SO42-+ 2Na+ +2Cl-
Explanation:
The balanced equation for the given reaction is:
Na2SO4+CaCl2======== CaSO4+2 NaCl
Na2SO4 will dissociate as 2Na2+ +SO4^2-
CaCl2 will dissociate as Ca2+ + 2Cl-
The two salts formed will precipitate.
we must consider that these substances are water soluble.
The ionic equation is:
2Na2+ +SO42-+2Cl-+ Ca2+----------- CaSO4+2NaCl
2Na2+ +SO42-+2Cl-+ Ca2+---------- Ca2+ + SO42-+ 2Na+ +2Cl-
They form molecules which can be in solution form if diluted in water, but some do form solutions on exposure to the atmosphere i.e they are deliquescent like pellets of sodium hydroxide
