PLEASE, PLEASE don't misspell insoluble. There is no such word as insoluable or soluable. The words you seek are soluble and insoluble.
The chemical you want is an acid. Add an acid (acetic acid or hydrochloric acid) and the CaCO3 will fizz but CaCl2 will not.
identify a chemical reagent that can be used to distinguish CaCl2 (soluable) from CaCO3 (insoluable). What is the distinguishing observation?
