Question

"Barium chloride reacts with aluminium sulphate to give aluminium chloride and a precipitate of barium sulphate".
(1).Translate the above statement into a chemical equation.
(2). state two types in which this reaction can be classified.

Answer 1

1) 3BaCl2 + Al2(SO4)3 =  2AlCl3 + 3BaSO4
2) This can be classified into 2 types: precepitation reaction and double displacement reaction

let me explain you  as we have
 3BaCl2 + Al2(SO4)3 produces 2AlCL3 +3BaSO4
becoz there are 2 aluminium and chloride so u make them into one and we also have 3 barrium and sulphate so u make them into another .....

hope it helps u.........

Answer 2

1》3BaCl2 +Al2(So4)3 =2AlCl3 +

3BaSo4  

2》The two types in which this reaction can be classified are

a》precipitate reaction

b》Double Displacement reaction
