Unformatted text preview: ______ of certain compounds. The solubility of lead chloride (PbCl 2 ) _______ as temperature reaches 100 C. Ammonium Hydroxide will force solid Silver Chloride (AgCl) _____ into solution. Using these properties, you can ______ the metal ions and thus determine which metals are present (or not present). Unknown! Tips Using 6M HCl careful! Add it slowly! NH 4 OH is NOT a strong base (as per lab manual) Put waste in correct containers. Rinse well with water into the waste container. Then wash in sink, put in bucket on back bench. Take labels off the test tubes when done. Dont forget to record unknown codes! Addition of chemicals When adding drop-wise make sure that you mix the chemicals between each drop. Agitate the test tube to ensure mixing !!!!!!!!!!!...
