WebCrystallization is a technique which chemists use to purify solid compounds. It is one of the fundamental procedures each chemist must master to become proficient in the laboratory. Crystallization is based on the principles of solubility: compounds (solutes) tend to be more soluble in hot liquids (solvents) than they are in cold liquids. Some of the important factors influencing solubility are: • Concentration • Temperature • Solvent mixture composition • Polarity laptop battery not charging asus
