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

Laboratory Preparation of Oxygen - Any of the above mentioned methods could be used to prepare oxygen in the laboratory. Mercuric and silver oxides are not used for the preparation of oxygen, as they are very expensive...

A peroxide is a metallic oxide which gives hydrogen peroxide by the action of dilute acids. They contain more oxygen than the corresponding basic oxide, e.g., sodium, calcium and barium peroxides. Dioxides like PbO 2 and Mn..

As hydrogen peroxide decomposes readily to give oxygen, it is used as a rich source of oxygen required to ignite liquid fuel in jet and rocket engines. It is used as a mild bleaching agent for bleaching delicate articles such as hair, silk, wood, etc. It is use..

In laboratory, oxygen can be produced by any one of the following method..

Introduce a small piece of sodium metal into a jar of oxygen. It combines with oxygen to form sodium peroxide. Allow a piece of sodium to burn in a deflagrating spoon, and then introduce it into another jar of oxygen. It burns w..

By treating sodium sulphite or bisulphite with dilute sulphuric acid or hydrochloric acid - The apparatus is set up as shown in figure 7.1. Sodium sulphite or bisulphite is taken in a round bottom flask. Dilute sulphuric or hydrochloric acid is added through the dropping funnel ..

The mode of addition of hydrogen bromide to unsymmetrical alkenes in the presence of oxygen and peroxides is contrary to Markownikoff rule. This addition of HBr to unsymmetrical alkenes against the Markownikoff's rule is known as peroxide effect, or anti-Markownikoff'..
