    and observed two peaks in my results. Therefore I concluded that cyclohexane was the low boiling point liquid. However‚ for the second liquid I guessed heptane first‚ and my results showed three peaks. Knowing that I had guessed wrong‚ I tested toluene mixed with my fraction C and only got two peaks. The high boiling point liquid proved to be

    ! 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
