Question

Which of the following will increase the solubility of CaSO4?

a. Adding H2SO4
b. Decreasing the pH
c. Adding HCI
d. Increasing the pH
e. Adding CaCl2 ogy

Answer 1

Decreasing the PH ( B )

Step-by-step explanation:

To increase the solubility of the compound CaSO4 we will need to decrease the PH level of the solution, this because the PH level of the solution CaSO4 is inversely proportional to the solubility of the solution

CaSO4 ⇄
`Ca^(2+) + SO^(2-)`
