Experimental Determination of Rate of Reaction - The rate of a reaction is determined by measuring the concentration of the reactant or product at different intervals of time. The concentration is measured, by measuring a related property such as color, pressure or volume (as in the case ..

Some Basic Concepts of Chemistry - A dynamic environment of matter and material surrounds man. Since his birth he has been exposed to these changing surroundings. His curiosity to understand his surroundings and the events occurring around him, has led him to systematically enquire and co..

The development of chemistry is based upon the systematic approach of the scientists in carrying out different experiments. Scientific theories, inferences and generalizations are made on the observations recorded. The quantitative information involves the measurement of one or more quant..

Atomic Structure and Chemical Bonding - Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It was observed that ..

Experimentally, it is found that the rate of a reaction is proportional to the concentrations of the reactants raised to some power, provided that other factors, which also affect the rate of the reaction are kept constant. For e.g., for the hypothetical reaction, the rate of reaction mig..

Xenon forms three fluorides, XeF 2 , XeF 4 and XeF 6 . These can be obtained by the direct interaction between xenon and fluorine under appropriate experimental conditions, The fluorides of xenon, XeF 2 , XeF 4 and XeF 6 react with fluoride ion acceptors like PF 5 , SbF 5 , AsF 5 to form ..

Depending upon the direction of the solvent travel, paper chromatography is termed as ascending or descending type. When the solvent travels upward on the paper, it is termed as ascending paper chromatography and descending paper chromatography when the solvent travels in the downward direction. ..
