So we did an experiment where we mixed Cacl2 and NaCl and then found the mass of the precipitate. Then we compared it to reference data on a standard curve to see the mass of Na2Co3 reacting to produce the CaCo3.

So what I'm stuck on is this:
Suppose the precipitate formed in a similar reaction is slightly soluble in water. Can a standard curve be used to determine the mass of reactant?

I just don't really get it, thank you for your help.

IDON'T GET IT EITHER. There is no reaction between CaCl2 and NaCl.
