Given the following drugs in a urine specimen: Cocaine alkaloid Secobarbital (a derivative of barbituric acid) Carisoprodol (a neutral drug) Devise an analytical flow chart that will be used to separate these substances from a urine specimen. The separation will be liquid extraction methods. Choose appropriate solvents and reagents based on the properties of the materials to be separated.

When dissolved in water, flunitrazepam, also known as roofies or the "date rape" drug, is difficult to detect because it is colorless, odorless, and tasteless. Recently, a straw has been developed that changes color when placed in a drink spiked with flunitrazepam. A woman at a bar is worried that flunitrazepam was slipped into her water when she left it unattended. She places one of these new color-changing straws into the water and the straw does not change color. Based on this result, is the woman's drink a pure substance or a mixture? mixture pure substance If it is a pure substance, is it an element or a compound? compound
