There are several hazards associated with the chemicals in the Electrochemical Cells experiment. For each chemical, list the letters of the associated hazards in the blank provided. Give the letters in alphabetical order, separated by commas. 3.0 M HCl B,E A. Toxic if ingested 3.0 M NaOH E B. Irritating vapors 0.1 M Cu(NO 3 ) 2 A C. Flammable 0.1 M AgNO 3 A,D D. Causes dark spots if spilled on skin Graphite rods F E. Corrosive Ascorbic acid (solid) F F. None Listed Select all statements that are correct with respect to waste disposal in the Electrochemical Cells Experiment. Cu 2+ solution and any solid that forms in Part B should be placed in the container for copper waste. Ascorbic acid solution can be flushed down the sink. A labeled beaker can be used to collect rinsings during the experiment. The electrodes should be discarded in the proper jar. Metal ion test solutions will be provided in containers and should not be discarded. Rinsings from the salt bridge can be flushed down the sink. No waste will be generated during this experiment. In Part C of the experiment, you will need to prepare 60 mL of a solution that is 0.10 M in sodium hydrogen phosphate heptahydrate (Na 2 HPO 4 ·7H 2 O, MW = 268.1 g/mol) and 0.10 M in ascorbic acid (C
