Detailed procedures for the cobalt thiocyanate test are available. The reagent consists of 2% cobalt thiocyanate dissolved in dilute acid. Glycerol is often added to stabilise the cobalt complex, ensuring it only goes blue when in contact with an analyte and not due to drying. Addition of the cobalt thiocyanate reagent to cocaine hydrochloride results in the surface of the particles turning a bright blue (faint blue for cocaine base). The solution changes back to pink up… WebApr 12, 2024 · In biology, a buffer is a solution that maintains a stable pH even if an acid or base is added. Biological buffers are made up of either a weak acid and its conjugate base, or a weak base and its conjugate acid. As the conjugate pairs exist in appreciable amounts at equilibrium, they’re able to neutralise small amounts of OH- (base) ions and ...
