Chemical Properties of water having biological significance. Water does not dissociate easily and hence, is an excellent solvent. It is also so because of its H-bonding capabilities and very high dielectric constant.

Essay on The Threat of Chemical Weapons to Humanity. After 9-11 -2001 there is a fear that the next major terrorist attack could be more lethal and that terrorist must use.
These are mainly due to various chemical substances from industry which get into public water supply. Usually they contain solvents, detergents, heavy metals, dyes, pigments, sulphides, organic substances etc.
The threat of chemical and biological warfare has been talked about frequently in the past years but the likelihood of such occurrence has assumed serious concern in the emerging terrorism dominated environment. Such tactics have been rightly given the name of Weapons of Mass Destruction (WMD).
The various ways through which chemical pollution is caused and their adverse effects have been discussed below: 1. From Industrial Wastes 2. Accidents in Chemical Factories 3. Excessive Use of Fertilizers 4. Use of Pesticides 5. Release of Gaseous Pollutants in Air 6. Pollution Caused by Dust.
During a chemical reaction, certain substances react together to form some new substances. A reaction is described in terms of the names and quantities of the reactants and products.
Chemical equation for a chemical reaction is written as follows: Identify the reactants and the products of the chemical reaction. Write down the formulae or symbols of the reactants only the left hand side with a sign of plus (+) between them.
A chemical equation can be made more informative by adding additional information to the chemical equation. This is done as follows:
A chemical equation should satisfy the following conditions: 1. Qualitative Information and 2. Quantitative information.
Chemical equations are balanced by adjusting the coefficients placed before the symbols or the formula of reactants and products. There are a few methods which can be used for the balancing of chemical equations.
