Answer 2

The answers to the questions given are as follows:

It is given that aqueous sodium hydroxide is added to the aqueous copper sulphate solution, which forms a bluish-white precipitate of copper hydroxide.

(a) The above reaction is of the type - Double Displacement Reaction.  

• The given reaction is a type of displacement reaction as displacement takes place in the given two solutions.
• Sodium ions can be seen getting displaced from the solution of sodium hydroxide and at the same time, copper ions can also be seen getting displaced from the solution of copper sulphate.

(b) The colour of the copper sulphate solution is blue.

(c) The balanced chemical reaction to represent the above reaction is written below:

$2NaOH+CuSO_{4} \rightarrow Na_{2}SO_{4}+Cu(OH)_{2}$
