Question

1) Write the balance equations for the following reactions and identify the type of
reaction in each case.
ii)Solution of barium chloride and sodium sulphate in water react to give insoluble
barium sulphate and the solution of sodium chloride.
iii) Aluminium react with Copper chloride to produce Aluminium chloride and
Copper.​

Answer 1

1) BaCl2 (aq) + Na2SO4 --> BaSO4(ppt.) + 2 NaCl (aq)

2) 2 Al + 3CuCl2 ---> 2 AlCl3 + 3Cu

Answer 2

${\red{\mathfrak{\boxed{\huge{ANSWER}}}}}$

1. BaCl2 (aq.) + Na2SO4 (aq.) -> 2NaCl(s) + BaSO4 (ppt.)
2. 2Al(s) + 3CuCl2(aq) -> 2AlCl3(aq) + 3Cu(s)

Reaction 1 is an example of double displacement reaction.

Reaction 2 is a displacement reaction.
