KINDS OF MATTER AND THEIR PROPERTIES Activity No. 5 I. OBJECTIVE: To learn how to distinguish an element, a mixture and a compound I. APPARATUS: Mortar and pestle, test tubes, glass tubing II. MATERIALS: Magnesium ribbon, sulfur antimony, iron filings, carbon disulfide IV. PROCEDURE AND OBSERVATION: 1. Observe the physical properties of sulfur and antimony at room temperature. Note their physical state, color and solubility in carbon disulfide. The solubility may be observed qualitatively by dissolving a pinch of the powdered samples in about 3 ml of carbon disulfide and stirring until the solid sample has dissolved. Record your observations in the table below. Solubility in CS, Classification of the sample (Element/Compound) Sample Physical Color State Sulfur Antimony a. Was the system formed by the addition of sulfur to CS, homogeneous or heterogeneous? b. Could its composition be varied or not? c. Explain your answer in 1a. d. Was the system formed by the addition of antimony to CS, homogeneous or heterogeneous? e. Explain your answer in 1d.
