How do i seperate 2 grams of calcium carbonate (powder) and barium sulfate (powder) in a school environment. its ok if i lose one of the powders. just need the weight of one to find percentage composition

[Hunter2]

Do a titration of calciumcarbonate with hydrochloric  acid. Bariumsulfate is not much soluble .

[Borek]

What will happen with both compounds when you treat them with any acid?

[ethansan]

The Calcium Carbonate Will react with the acid, whilst the BaSO4 will not react (in theory) as defined by its properties

[ethansan]

Within a titration experiment between CaCO3 and HCl, if the amount of CaCO3 is unknown, is it possible to find out the mass of the CaCO3 using how much HCl was used to fully react with CaCO3? If so, how would the process work?

@Ethansan

CaCO₃ is pretty much insoluble (0.013g/l according to Wikipedia) so you might want to look into back titration. Also bear in mind that HCl is not a primary standard and should be standardised to be strictly correct.

Before we will worry about nitty gritty details of titration methods (which are great BTW), let's see what can be done with the simplest methods available.

The Calcium Carbonate Will react with the acid, whilst the BaSO4 will not react (in theory) as defined by its properties

Right.

So, assuming you added some acid, what is the leftover solid?

If you have a solid and a solution, can you separate them?

we would have BaSO4 left over in a solution of CaCl2, but we're not sure how to remove the solid from the liquid

Do you know Filtration?
