Question

"Barium Chloride reacts with Aluminium Sulphate to give aluminium Chloride and a precipitate of Barium sulphate"

1) translate the above statement into chemical equation.
2) state two types in which this reaction can be classified.

Answer 1

Answer:

3Bacl2+Al2(SO4)3=2AlCl3 +3BaSO4

Double displacement reaction

Redox reaction

Answer 2

Answer:

From the above given question we can see that, on reaction of Aluminium sulphate with Barium chloride , it gives two products - Aluminium chloride and a precipitate of Barium sulphate.

1) This above statement is written in the form of chemical reaction as follows:

Al2(So4)3 + 3Bacl2 -> 2Alcl3 + 3 Ba(So4)

2) The above given reaction is of two types.

i) It is a precipitation reaction as precipitation of Barium sulphate is noted at the end of the reaction.

ii) This is also a displacement reaction, as Sulphate and Chloride gets displaced from the original molecules and combines with other molecules to form a new substance at the end of the reaction.
