Question

A solution has been prepared by dissolving 5g of copper sulphate. Calculate the mass
percentage of copper sulphate solution at room temperature​

Answer 1

Answer:

solution leave on evaporation and drying 1.2 g of anhydrous CuSO

4

in water at 25

o

C is 25.

Easy

Answer

100 g of dilute solution of CuSO

4

contain

=1.2×10=12.0gCuSO

4

Mass of water present in dilute solution

=(100−12)=88g

To saturate 100 g of water, CuSO

4

required = 25 g

So, to saturate 88 g of water, CuSO

4

required =

100

25

×88=22g

Thus, the mass of CuSO

4

to be added to 100 g of dilute solution to saturate it =(22−12)=10g.
