Recrystallization is the process in which a chemical compound becomes a solid. The difference between recrystallization and the presence of precipitate is the structure. In Cystristalizatqion the solid compound contain a crystal-like structure. According to Hill and Barbaro the most common method of purifying organic compounds. Not only does recrystallization allow people with the ability to converting organic molecules to crystal-like solids. This process is performed in the creation of rock candy

A Clockwork Orange The freedom of choice and the rehabilitating form of corrections encase the realm of A Clockwork Orange‚ by Anthony Burgess. It produces the question about man’s free will and the ability to choose one’s destiny‚ good or evil.

Each substance was tested with the indicators red litmus paper‚ blue litmus paper‚ pH paper‚ phenolthalein‚ bromthymol blue‚ and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper‚ the phenolthatein‚ bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance
