    ! Isolation of the Components of BC Powder Introduction Aspirin‚ Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this‚ the three components were forced into conjugate acid (or base) forms‚ causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel
