    What is the difference between an emulsion and a colloid?

    <p>An emulsion should be used when both phases, dispersed and continuous, are liquids, while colloids are a more general class of two-phase systems of matter.</p> Signup and view all the answers

    What are the two types of emulsions formed by oil and water?

    <p>Oil and water can form an oil-in-water emulsion, with the oil as the dispersed phase, and water as the continuous phase, and a water-in-oil emulsion, with water as the dispersed phase and oil as the continuous phase.</p> Signup and view all the answers
