this is a sample question like it

Four tests will be investigated: Melting Point Analysis, Melting Point Range Analysis, Iron (III) Chloride Test, and TLC analysis. What 3 tests (the same test may be in both questions 4 and 5) will be performed to assure the synthesized crystals do not contain contaminates like salicylic acid (purity of synthesized crystals)? Explain the positive results of each test. 4. Four tests will be investigated: Melting Point Analysis, Melting Point Range Analysis, Iron (III) Chloride Test, and TLC analysis. What 2 tests (the same test may be in both questions 4 and 5 ) will be performed to determine if the synthesized crystals are aspirin (identity of synthesized crystals)? Explain the positive results of each test. 1. melling point analysis: determines the purity of a compaund and to compare its melting point to the known melting pant. Known welting point is 135136C 2. Iron (III) chloride restidetects the presence of a carboxylic acid, which is present in aspirin
