Salicylic acid the OH group is "ortho" to the carboxyl group. It is also known as 2-hydroxybenzoic acid. It is poorly soluble in water (2 g/L at 20 °C). Aspirin (acetylsalicylic acid or ASA) can be prepared by the esterification of the phenolic hydroxyl group of salicylic acid with the acetyl group from acetic anhydride or acetyl chloride. Salicylic acid can also be prepared using the Kolbe-Schmitt reaction. Salicylic acid is used as a food preservative, a bactericidal and an antiseptic. Sodium salicylate is a useful phosphor in the vacuum ultraviolet spectral range, with nearly flat quantum efficiency for wavelengths between 10
Cupboard love by physiologist, Ivan Pavlov. It supports assumptions that form the foundation of behaviorism. These basic ideas suggest that all learning occurs through interactions within the environment, and that environment shapes behavior. Various similarities exist between cupboard love and classical conditioning. Pavlov, known for Pavlov's dog experiment, discovered that his dog would salivate at the sound of a bell, associating the ringing with food. Eventually, the dog would salivate each time he heard the bell ring. When there was no food, the dog would still show affection to Pavlov in an attempt to be fed. Similarly, the cupboard love theory suggests
