    Study Notes

    • Milk is a colloid, a type of heterogeneous mixture, where butterfat globules are suspended in water.
    • Mixtures can be homogeneous or heterogeneous, and separating them depends on their components' properties.
    • Homogeneous mixtures require specialized separation techniques, while heterogeneous mixtures can often be separated by simple physical means.
    • Methods for separating mixtures include chromatography, distillation, evaporation, crystallization, filtration, dissolving, magnetism, and manual separation.
    • Chromatography is a separation technique that utilizes the difference in affinity between components and a stationary/mobile phase.
    • Paper chromatography is a simple version of chromatography, where ink is placed on a piece of chromatography paper, and a solvent is used to move the mixture components.
    • In paper chromatography, components of a mixture travel different distances from the starting point, depending on their affinity for the stationary and mobile phases.
    • Distillation is a separation technique for liquids, where components are separated based on their different boiling points.
    • Evaporation is a technique for separating solids from liquids, where heat is added to cause the liquid to evaporate, leaving behind the solid.
    • Sugar can be separated from a sugar-water mixture by heating, which causes the liquid to evaporate, leaving behind the solid sugar.
