Question

Q2. State your observations in the following
when sodium hydroxide solution is added to copper sulphate solution
​

Answer 1

Answer:

NaOH is a strong base while CuSO4 is an acidic salt. When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulphate will be formed.

C. E.

2NaOH + CuSO4 --> Cu(OH)2 + Na2SO4.

This is a double displacement as well as precipitation reaction.

Answer 2

Pale Blue colour precipitate will be observed when Sodium Hydroxide solution is added to Copper Sulphate solution.

Explanation:

NaOH is a strong base while CuSO4 is an acidic salt. When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulphate will be formed.

Reaction of Sodium Hydroxide solution with Copper Sulphate solution.

2NaOH + CuSO4 --> Cu(OH)2 + Na2SO4.
