The mass percentage of each constituent element present in any compound is called its percentage composition. This may be obtained from the molecular formula of the compound by using the relationship:..

Indicators are substances, which indicate the completion (equivalence point or end point) of a chemical reaction by change in colour. For example, in volumetric analysis, during the titration of sodium hydroxide and hydrochloric acid (taken in the burette), phenolphthalein turns..

Introduction - Organic compounds are isolated either from natural sources or from reaction mixtures. These compounds are seldom pure and are usually contaminated with small amounts of other similar compounds, which are found to exist together or formed during the reaction. In order to characterize ..

2 SO 4 Sulphuric acid is used in large number of industries. It is called the "King of chemicals". Its important uses are: i) As an acid in laboratories and industries. ii) In storage batteries and lead accumulators. iii) In chemical industries for the preparation of h..

>Green chemistry encompasses all aspects and types of chemical process including synthesis, catalysis, analysis, monitoring, separations and reaction conditions, which reduce or eliminate the use or generation of hazardous substances. Green chemistry technologies can be categori..

. When the electrodes were connected they produced a high energy spark of about 75,000 volts. Spark Discharge Apparatus Prior to the experiment, Urey and Miller evacuated the entire apparatus. Through the inlet, they passed a mixture of ammonia, methane and hydrogen in the ratio of 2:2:1 by volume...

Nerve Net of HydraThe nervous system is made up of units called the neurons which relay information by generating electric potential. The endocrine system, on the other hand, is made up of glands that secrete chemicals called the hormones. They are secreted into blood that carries them to..
