Question
Experiment 16 involves determining the identity of 6 unknown household products.
Available tests:
1: Solubility in water
2: pH
3: AgNO3 (aq)
4: PbNO3 (aq)
5: BaCl2 (aq)
6: 1M HCl (aq)
7: 1M NaOH (aq)
8: Iodine
9: Acetic acid (aq)
10: Flame test
Complete the required portions of the table in blue, and any number of additional experiments in yellow, by selecting the corresponding active ingredient for the following household products from set C and match the corresponding result for each selected test. Before coming to lab: Download and print table. Fill in with the experiments you will be performing and expected results for that test. Click here to download your Set C Household Product Sheet Some references include your lab manual, solubility rules from table 9.1, Merck Index or CRC Handbook (available in the Resource Centre).
***Please Note: This question and answer already exsists on Chegg however the answers are incorrect according to CAPA. Please help based on photos attached (All the blue are correct so the rest of the answers should be based on that).
