1. Write balanced net ionic equations for the following reactions: a) The precipitation of the chloride of Hg22+ in Step 1. Step 1. Precipitation of the Group I Cations. Add two drops of 6 M HCI to 1 ml of the known solution in a test tube. Mix the solution thoroughly with a stirring rod. Centrifuge the mixture. (Remember to always place a similar sized test tube containing an equal amount of water in the opposite holder of the centrifuge.) Two minutes of spin time is USsually sufficient to separate the precipitate from the solution. Place another drop of 6 M HCI in the test tube to ensure complete precipitation and centrifuge again if necessary. Decant the supernatant liquid into another test tube and save for further tests. (Be sure to label the test tube appropriately for later identification.) The original test tube will contain white precipitates which are the chlorides of the GroupI cations.
