Question

\[{H_2}{O_2}\] in the rocket has the concentration?
(A) 50%
(B) 70%
(C) 30%
(D) 90%

Answer 1

Hint: \[{H_2}{O_2}\] stands for hydrogen peroxide. It is a colourless liquid with both oxidation and reduction properties in acidic and basic mediums. This property allows it to offer a wide variety of uses and applications.

Complete Step by Step Solution:
\[{H_2}{O_2}\] or Hydrogen peroxide is the simplest peroxide that is available. It is a colourless liquid that is widely used as a bleaching agent. It is often dissolved in the aqueous medium for safety in handling purposes.
The concentrated form of \[{H_2}{O_2}\] or hydrogen peroxide is used as a propellant for the rocket industry with the concentration that is used is 90%.
Hydrogen peroxide is acidic in nature with a ph of about 4.5 and it is a 100% biodegradable compound. It is also known as water with an extra oxygen atom.
\[{H_2}{O_2}\] exhibit certain physical and chemical properties such as:
1) Hydrogen peroxide is very pale blue or colourless in appearance in its pure state.
2) The boiling point of hydrogen peroxide is 423K and the melting point is 272.4K .
3) It always hydrates and is soluble in water in almost all concentrations or proportions.
4) It also has very strong bleaching properties and has the tendency to bleach silk, wool, cotton, and hair.

Note: Hydrogen peroxide has the tendency to degenerate when it comes in contact with direct sunlight, so its storage should be proper. The proper way to store it is that it should be kept in plastic containers or glass containers that are lined with wax. It should be kept in the dark. It should also be kept away from dust particles as it can lead to explosive reactions.
