Scott test is one of the methods used for screening for Cocaine in Forensic Chemistry. The multi step method consists of a) reacting the sample drug with cobaltous thiocyanate b) dissolving of the formed precipitate by adding HCl and c) extraction of coordination compound with Chloroform d) measurement of absorbance of extracted coordination compound at 627 nm All the reactions in this multistep method are not fully understood. However, it was determined that there are 2 moles of cocaine in coordination compound measured in last step. If coordination compound is represented as “Scott” coordination compound, which of the following is correct “stoichiometric” factor to get mass of cocaine from mass of measured complex ? a.g (Scott coordination cpd) * MM (Scott coordination cpd) MM (cocaine) b.g (Scott coordination cpd) * 2 *MM (Scott coordination cpd) MM (cocaine) c. (Scott coordination cpd) * MM (Scott coordination cpd) 2* MM (cocaine) d.g (Scott coordination cpd) * 2 Molar Mass (cocaine) MM (Scott coordination cpd)
