Question

On heating 10L saturated solution of Na2SO4, 284g of residue is found . Find Ksp of Na2SO4?​

Answer 1

Explanation:

Thank you and stay safe and enjoy

Answer 2

Solubility product Ksp is determined to be 0.5

Solubility product is given in units of moles per litre. It is also known as molar solubility.

Explanation:

Thus solubility product =Mole/L

Na2SO4 =molecular weight  will be 142

Moles involved =Residue found/Molecular weight

Given residue found is 284g

Mole involved =284/142

= 2 moles

Solubility product =Moles/L

Here 10L solution is heated so Ksp=Moles/L

Ksp=2/10

Ksp =0.5

Solubility product Ksp is determined to be 0.5
