Question

Translate the following statement into chemical equation and then balance it
Barium chloride solution reacts with aluminium sulphate solution to form a precipitate of barium sulphate and aluminium chloride solution.

Answer 1

$3BaCl_{2}+Al_{2} SO_{4} +2H_{2}SO_{4}-->2AlCl_{3}+3BaSO_{4}+4H^+$

Explanation:

We are supposed to write and balance the equation of Barium chloride solution reacts with aluminium sulphate solution to form a precipitate of barium sulphate and aluminium chloride solution.

The the valence state of barium is +2 and that of aluminium is +3.

The reaction would be ,

$BaCl_{2}+Al_{2} SO_{4}-->AlCl_{3}+BaSO_{4}$

So this is the basic equation for the abow process now balancing we get,

$3BaCl_{2}+Al_{2} SO_{4} +2H_{2}SO_{4}-->2AlCl_{3}+3BaSO_{4}+4H^+$

Hence this is the balanced equations of the reactants and products.

Answer 2

Balanced chemical reaction:

$\bold{3 B a C l_{2(a q)}+A l_{2}\left(S O_{4}\right)_{3(a q)} \rightarrow 3 B a S O_{4(s)} \downarrow+2 A l C l_{3(a q)}}$

Explanation:

• In above reaction the barium sulphate is formed as precipitate. So, this is a precipitation reaction and the physical state of the products and the reactants are mentioned in the above reaction.
• In this reaction, the position of the chloride with barium and sulphate with aluminium is interchanged to form barium sulphate and aluminium chloride. So, this is also a double displacement reaction.

Uses:

• Barium sulphate is used as drilling agent, plastic filler, and radiocontrast agent.
• Aluminium sulphate is used in water purification and as coagulating agent.
