Lab 2, Week 2 BOND LAB Introduction The purpose of this lab is to find and learn the properties of ionic and covalent bonds, also to learn the physical properties of each substance; such as melting point, solubility and conductivity, type of bond in the compound. Also in this experiment, tests on these properties will be performed enabling the classification of compound bonds as ionic or covalent. Procedure Part A - Melting Point 1. Obtain six watch glasses. Place a two-gram sample of the following compounds in a separate watch glass: * Watch Glass #1: 2g of Calcium Chloride * Watch Glass #2: 2g of Citric Acid * Watch Glass #3: 2g of Phenyl Salicylate * Watch Glass #4: 2g of Potassium Iodide * Watch Glass #5: 2g of Sodium Chloride * Watch Glass #6: 2g of Sucrose 1. Under each watch glass place a Bunsen burner. 2. In the chart provided in the observations section, record the order of melting. If the compound does not melted after 2 minutes put “no” in the table. Part B - Solubility in Ethanol 1. Obtain six test tubes and add 25ml of ethanol to each test tube. 2. Add a two-gram sample of each of the above compounds to each test tube. 3. Stir the samples. 4. In the chart provided record if each compound is solubility in ethanol. Part C - Solubility in Water 1. Obtain six test tubes and add 25ml of water to each test tube. 2. Add a two-gram sample of each of the above compounds to each test tube. 3. Stir the samples. 4. In the chart provided record if each compound is solubility in water. Part D - Conductivity 1. Obtain six 100ml beakers and add 50ml of water to each. 2. Place a 10g sample of each of the above compounds in a separate beaker. 3. Obtain six conductivity meters. Measure and record the conductivity of each solution. Observations and Results Table 1: Give the table a title.
