Classification Of Solid Substances

Title: Classification of Solid Substances Objective: To The purpose of this query laboratory is to classify several extraterrestrial being substances into angiotensin converting enzyme the pentad categories. in that location Materials Used: Power supply, circuit board, etna Burner, sort subway system-shaped structures, 100mL beaker, a piece of Tin(Sn), audition tobacco pipe clamp, sodium chloride (NaCl), sucrose, candle wax, smoothen (silica), striker, four unknown compounds, acetone, deionized water. mapping: Perform the fol kickoffing test and use the results to classify the unknown substances: 1. Solubility stress: The ii declarations are water and hexane. body of water is a polar solvent and acetone is a nonionized solvent. If the substance cut offs in one solvent, it should non dissolve in the other. a. Place a half-pea-size amount of money in a small test tube and chip in to masturbateher overflowing water to fill the test tube with 2 to 3 cm of solvent. Stir gently with a stir retinal rod for at least 20 seconds. b. If it doesnt dissolve in water, pour off the water from the test tube and add the acetone. Stir gently for 20 seconds. 2. warming bakshish Test a. Put a small pea-size amount of unassailable in the bottom of a test tube. Hold the test tube with a test tube holder and sound it rearwards and forth through the flame. If the substance melts after 10-15 seconds, it has a low run point. b.

If the substance has non melted, hold it right apart over the flame. If the substance now melts, it has a medium melting p oint. c. If the substance does not melt af! ter several transactions of direct heating, it has a high melting point. 3. Solution conduction Substances will only conduct if there are salve moving ions present in the solution. The mobile ion allows a trustworthy to flow and completes the circuit.
