Question

write a balanced chemical equation a solution of Barium Chloride and sodium sulphate in water reacts to give insoluble Barium sulphate and the solution of sodium chloride

Answer 1

Balanced chemical equation denoting the reaction of Barium Chloride and sodium sulfate

• The word equation given in the reaction is:

Barium Chloride + Sodium sulfate → Barium sulfate + sodium chloride

• The chemical equation for the given word equation is:

$BaCl_2+Na_2SO_4\rightarrow BaSO_4+NaCl$

• When the number of atoms for the reactant side is calculated it gives:

Ba = 1

Cl = 2

Na = 2

S = 1

O = 4

• When the number of atoms for the product side is calculated it gives:

Ba = 1

Cl = 1

Na = 1

S = 1

O = 4

• The obtained result indicates that the chlorine and sodium atoms are not equal on both sides. Thus the reaction is not balanced.
• The balanced reaction has the number of atoms involved in reaction in reactants as well as the product as equal.
• To make both side equal some changes must be made as shown in the balanced equation is:

$BaCl_2+Na_2SO_4\rightarrow BaSO_4+2NaCl$

• For the above equation, the number of atoms in the reactant is:

Ba = 1

Cl = 2

Na = 2

S = 1

O = 4

• The number of atoms in product is:

Ba = 1

Cl = 2

Na = 2

S = 1

O = 4

• As the number of atoms in the reactants side is equal to the number of atoms in the product side, the reaction is balanced.
