After doing the drawing our first watercolor painting step is painting the sky and clouds. Create a very weak mixture of French Ultramarine and Burnt Sienna, about the strength of a weak cup of tea.
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. A polar molecule with two or more polar bonds must have an asymmetric geometry so that the bond dipoles do not cancel each other.
Non-Polar: A molecule that does not posess a dipole because of the arrangement of molecules. This affects the rate of dissolving and solubility because of the intermolecular forces of particles. Polar compounds dissolve in Polar solvents, Non-Polar compounds dissolve in Non-Polar solvents.
