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 [...]
The following points highlight the top 6 methods for deduction of radioactivity. The methods are: 1. Ionization 2. Ionization Chambers 3. Gesger Counters 4. Semi-Conductor Detectors 5. Scintillation 6. Autoradiography. 1. Ionization: The passage of high energy radiation through matter results in the formation of ions as a result of collision of electrons with atoms. So much energy is transferred [...]
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 [...]
