The substance NaCL, Na2CO3+, MgSO4+, and NH4Cl, which are used for test solutions are soluble ionic compounds. Solid CaCL2 and solid CaCO3 can be distinguished by the use of HCl. 10 2. What is the distinguishing observation? Silver nitrate can be used to distinguish between the two. Cl- salt will form a white precipitate and SO4 will form clear crystals. 2017/2018. When CaCl2 is treated with HCl, no changes will occur but when CaCO3 comes in contact with HCl their will … of a compound. Depending upon the tip of a dropper pipet, there are approximately 20 drops per milliliter of water. The experimental procedure, Parts A and B, indicates the addition of 5-10 drops of each solution to the test tubes. Chemical Properties of Known Compounds, Compound in Unknown Solution: NaOH + MgSO.
