Question

Which chlorine oxide is used as a bleaching agent for paper pulp and textiles?
A.\[Cl{{O}_{2}}\]
B.\[C{{l}_{2}}O\]
C.\[C{{l}_{2}}{{O}_{6}}\]
D.\[C{{l}_{2}}{{O}_{7}}\]

Answer 1

Hint: Bleaching can be defined as a process of whitening fabric by removal of natural colour and it is usually carried out by means of chemicals selected according to the chemical composition of the fibre. Chemical bleaching is generally accomplished by oxidation, destroying colour by reduction of the organic matter.

Complete step by step answer:
Chlorine dioxide, \[Cl{{O}_{2}}\] ​ is used as a bleaching agent for paper pulp and textiles. It is also used for treatment of water. \[Cl{{O}_{2}}\] is quite powerful and must be diluted with water for safe use on most of the fabrics. Chlorine dioxide is a neutral chlorine compound which is produced as a gas and it is saturated in water. Chlorine dioxide is about 10 times more soluble in water than hypochlorite. As such, it is widely used as a bleaching agent and is a potent antimicrobial chemistry. When chlorine bleach is used for laundry, the chemical ingredient oxidizes in water so as to remove soil and organic matter from the fabrics.
 Hence, correct answer is that \[Cl{{O}_{2}}\]is used as bleaching agent in pulp and textile industry which is option A.

Note:
Hydrogen peroxide is one of the most common bleaching agents. It is used as the primary bleaching agent in the textile industry, and is also used in pulp, paper, and many home laundry applications. Alkaline hydrogen peroxide is used as a bleaching agent for the mechanical pulp. The amount of base such as sodium hydroxide is less than that which is used in bleaching chemical pulps and the temperatures are lower.
