Question

calculate the solubility of copper sulphate at zero degree centigrade if 7.15 gram copper sulphate dissolves in 50 grams of water to form saturated solution​

Answer 1

Answer:

Explanation:

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.
