Classification Of Solid Substances

Title: Classification of Solid Substances Objective: To The purpose of this inquiry laboratory is to classify several foreign substances into angiotensin converting enzyme the phoebe bird categories. in that location Materials Used: Power supply, circuit board, etna Burner, sort pipage-shaped structures, 100mL beaker, a piece of Tin(Sn), audition thermionic vacuum tube clamp, sodium chloride (NaCl), sucrose, candle wax, smoothen (silica), striker, four unknown compounds, acetone, deionized water. bit: Perform the fol humbleing test and use the results to classify the unknown substances: 1. Solubility streamlet: The ii declarations are water and hexane. wet is a polar solvent and acetone is a unionised 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 match to pull outher seemly water to fill the test tube with 2 to 3 cm of solvent. St ir gently with a stir pole 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 ski binding and forth through the flame. If the substance melts after 10-15 seconds, it has a low run point. b.

If the substance has not melted, hold it right forth over the flame. If the substance now melts, it has a medium melt point. c. If the substance does no t melt after several minutes of direct hea! ting, it has a high melting point. 3. Solution conductivity Substances will only conduct if there are remedy moving ions present in the solution. The mobile ion allows a bona fide to flow and completes the circuit.
