Definition of Viscosity: The resistance experienced by one layer of a liquid in moving over another layer is called "viscosity". Viscosity varies greatly. Ether and gasoline have little viscosity and are quite mobile. But honey and coal-tar have high viscosities. The unit of viscosity is the "Poise", [...]
The following points highlight the top sixteen properties of acidity and alkalinity. 1. The reaction of the tissues and tissue fluids of the body is nearly natural excepting gastric juice. The slight changes in reaction have a significant physiological effect. In case the reaction of the solution is made slightly more acid or more alkaline, the heart stops. 2. Acidity [...]
Indicators: Definition, Characteristics and Uses! Definition: Certain dyes which can determine the hydrogen ions in a solution are said to be Indicators. Characteristics: 1. The dyes are weak acids (or, less commonly, weak bases). 2. They have the property of dissociating in solution to yield ions of different colours from the un-dissociated molecules. 3. The pH at which dissociation will [...]
