LAB REPORT IDENTIFYING AN UNKNOWN COMPOUND PURPOSE To determine the properties of six compounds and design an experiment to identify an unknown substance. PROCEDURES Baking soda (sodium bicarbonate, gG±²³ ´ ), washing soda (sodium carbonate, gG µ ²³ ´ ), chalk (magnesium carbonate, ¶·²³ ´ ), table salt (sodium chloride, gG²¸ ), cornstarch and Epsom salt (magnesium sulphate heptahydrate, ¶·¹³ º » 7± µ ³ ) were tested for five different characteristics: solubility in water, reaction with acetic acid, reaction with tincture of iodine, reaction with sodium hydroxide (with water mixture) and reaction with phenolphthalein (with water mixture). The results of these tests were placed in a table (Table 1) for use later. The next part of this experiment is to test six unknown compounds using the information found in the previous step. This, however, can only be done if there is a constant procedure that can be used for each of the unknowns, that will in the end yield the identity of the compound. My procedure took the form of a flow-chart:
