# Write down the molecular and ionic equations for the exchange of barium chloride with each

Write down the molecular and ionic equations for the exchange of barium chloride with each of the indicated substances: a) sulfuric acid; b) sodium sulfate; c) calcium sulfate

Let us write down the equation for the reaction between barium chloride and sulfuric acid.

BaCl2 + H2SO4 = BaSO4 + HCl

Let’s arrange the coefficients:

BaCl2 + H2SO4 = BaSO4 + 2HCl

Let us write down the complete and abbreviated reaction equations.

Ba ^ (2+) + 2Cl ^ (-) + 2H ^ (+) + SO4 ^ (2-) = BaSO4 + 2H ^ (+) + 2Cl ^ (-)

Ba ^ (2+) + SO4 ^ (2-) = BaSO4

Let us write the reaction equation for the interaction of barium chloride and sodium sulfate.

BaCl2 + Na2SO4 = BaSO4 + NaCl

Let’s arrange the coefficients:

BaCl2 + Na2SO4 = BaSO4 + 2NaCl

Let us write down the complete and abbreviated reaction equations.

Ba ^ (2+) + 2Cl ^ (-) + 2Na ^ (+) + SO4 ^ (2-) = BaSO4 + 2Na ^ (+) + 2Cl ^ (-)

Ba ^ (2+) + SO4 ^ (2-) = BaSO4

Let us write down the reaction equation for the interaction of barium chloride and calcium sulfate.

BaCl2 + CaSO4 = BaSO4 + CaCl2

Let us write down the complete and abbreviated reaction equations.

Ba ^ (2+) + 2Cl ^ (-) + Ca ^ (2+) + SO4 ^ (2-) = BaSO4 + Ca ^ (2+) + 2Cl ^ (-)

Ba ^ (2+) + SO4 ^ (2-) = BaSO4
