Question

1.increasing the temperature increases the rate of a reaction by dissolution of solid in liquid.

2.Tyndall effect is the ability of homogeneous mixtures to scatter light​

Answer 1

1. For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

2. The Tyndall Effect is the effect of light scattering in colloidal dispersion, while showing no light in a true solution. This effect is used to determine whether a mixture is a true solution or a colloid.
