hydrogen peroxide solution is added to acidified potassium iodide solution

It is customary to indicate the strength of a sample of hydrogen peroxide solution in terms of the 'volume of oxygen at NTP that one volume of hydrogen peroxide gives on heating'. When the grade of H 2 O 2 in volumes ..

Sodium peroxide is added to an ice-cold dilute solution of sulphuric acid (20 %), in small doses at a time...

Chemical Properties of Hydrogen Peroxide - Hydrogen peroxide has an interesting chemistry because of its ability to function as oxidant as well as a reductant in both acid and alkaline solutions. The oxidation state of oxygen in hydrogen h..

Hydrogen peroxide has an interesting chemistry because of its ability to function as oxidant as well as a reductant in both acid and alkaline solutions. The oxidation state of oxygen in hydrogen peroxide is -1. It can therefore be oxidized to ..

Gold being a noble metal occurs in its native form. It is further purified by the process of leaching or precipitiation called hydrometallurgy. The native gold in its complex form is first precipitated with potassium cyanide solution. It is then recovered from the solution..

Water as such is a neutral stable molecule. It is difficult to break the covalent O-H bonds easily. Hence, electrical energy through the electrolysis process is applied to separate dioxygen from water. When a small amount of acid is added to water ionization is initiated which ..

Formula mass of KNO 3 = (39 amu + 14 amu + 3 x 16 amu) = 101 amu Then, ..

Potassium dichromate = K 2 Cr 2 O 7 GMM = (2 x 39) + (2 x 52) + (7 x 16)= 78 + 104 + 112 g = 294..

. Lithium aluminium hydride (LiAlH 4 ) is a powerful reducing agent commonly used in organic synthesis. Sodium is used as a reagent to detect the presence of nitrogen, sulphur and halogens by Lassaigne's extract method. It is also used for the preparation of sodamide (NaNH 2 ), ..

Aquatic life in water depends upon the presence of dissolved oxygen. Unless a minimum amount of the dissolved gas is present in lakes and rivers, fish and other aquatic life will die. Many pollutants in the water are biodegradable and some are non-biodegradable. Complex molecules, which are broken..
