Networking. Organizations have a networking relationship when they exchange information in order to help each organization do a better job. For example, if a school and a community counseling center share information about their counseling services for youth, that is a form of networking.
Phenolâchloroform extraction is a liquid-liquid extraction technique in biochemistry and molecular biology for purifying nucleic acids and eliminating proteins. In brief, aqueous samples are mixed with equal volumes of a phenol: chloroform mixture.After mixing, the mixture is centrifuged and two distinct phases are formed, because the phenol: chloroform mixture is immiscible with water.n brief, aqueous samples are mixed with equal volumes of a phenol: chloroform mixture.

Phenolphthalein is often used as an indicator in acidâbase titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. Phenolphthalein is slightly soluble in water and usually is dissolved in alcohols for use in experiments.It is a weak acid, which can lose H + ions in solution. The phenolphthalein molecule is colorless, and the phenolphthalein ion is pink.When a base is added to the phenolphthalein, the molecule â ions equilibrium shifts to the right, leading to more ionization as H + ions are removed.This is predicted by Le Chatelier's principle.henolphthalein is slightly soluble in water and usually is dissolved in alcohols for use in experiments.
