1. Although not part of the SI system of units, the angstrom (A) is exactly equal to 10-10 m or 10-8 cm. The limits of the colloidal range is from 1-1000 nm.How do you express this range in angstrom units?
2. (answers to the other four questions would also be appreciated)

1. Identify the three types of dispersions. 2. How does a colloidal dispersion differ from a true solution? 3. Although not part of the SI system of units, the angstrom (A) is exactly equal to 1010m or 108cm. The limits of the colloidal range is from 11000nm. How do you express this range in angstrom units? 4. Explain the result of the dialysis tubing experiment. What did it prove in terms of the permeability of the membrane and the size of the particles in question? 5. Explain the Tyndall effect. How can it be used to differentiate a solution from a colloid or suspension
