Hii dear,

# Step-by-step Solution-
First add dil.HCl to both samples

1) If bubbles appear, the sample is CaCO3-
- We can confirm this by adding phenolphthalein indicator to the mixture, CaCO3 will turn it pink

2)1) If bubbles don't appear, the sample is CaSO4-
- We can confirm this by adding BaCl2 to the mixture, CaSO4 will form precipitate BaSO4 that won't dissolve in dil.HCl.

Thanks for asking this...
