Itis the interaction of silver nitrateand sodium chloride (common salt).The substances may be recognizedby the form of the crystals of whichthey consist. The latter is composedof small cubes (Fig. 6), while theformer presents a less familiar formgeometrically (Fig. 7). Both sub-stances are capable of being dis-solved in water and, for this experi-ment, portions of each substance are shaken in separate vessels with water, until none of the solid the solutions are now poured together, we observ
