nitrate determination method

Nitrates are the most important salts of nitric acid. Some of the methods for the preparation of nitrates are given bel..

A small known mass (0.2 to 0.3 g) of the given organic compound is heated with fuming nitric acid and a few crystals of silver nitrate at about 200C in a sealed tube (called Carius tube) for 5 to 6 hours. Carbon and hydrogen are oxidized to carbon dioxide and water while halogen forms a ..

, and from (iv) the general solution of q is determined..

For determination of the order of a reaction, following methods are usually employed. a) Graphical Method b) Initial Rate Method c) Ostwald Method of Isolatio..

First, the data of concentrations versus time is obtained by a suitable method. Then, the data is plotted as concentration versus time. From the resulting plot, the instantaneous rates are determined by drawing tangents to curve and then calculating their slopes. The react..

is too small in the view of the large astronomical distance and the place of observation. Hence, in order to have a better and valid point of observation, two points on the surface of the Earth is taken as the basis for observation instead of the two eyes. In order to have simultaneous observatio..

In this method, a complex with the metal atom in a higher oxidation state than the starting material is obtained. Example:..

Volumetric method is used for determining the molecular masses of acid and bases. In this method, a known mass of the acid is dissolved in water or neutral alcohol, and the solution is titrated against a standard solution of an alkali using phenolphthalein as the indi..

For reactions where many reactants are involved, the order of the reaction is determined by the method of isolation. This was developed by Ostwald. In this method, the concentrations of all the reactants except one are taken in excess. For e.g., in the reaction A + B +..
