Why does chlorine show bleaching action?
Why does chlorine show bleaching action?
Nascent oxygen is a more powerful oxidising agent. Its formation is responsible for the bleaching nature of chlorine in the presence of moisture.
Why does Cl2 act as a bleaching agent?
Chlorine reacts with water to form hydrochloric and hypochlorous acids. Hypochlorous acid is unstable, and it easily dissociates to form nascent oxygen. Its formation is responsible for the bleaching nature of chlorine in the presence of moisture.
Why chlorine acts as a bleaching agent only in the presence of moisture?
Coloured material +[O]→ Colorless material. Therefore, chlorine acts as a bleaching agent only when moisture is present.
Why bleaching action of chlorine is permanent and so2 is temporary?
Why bleaching action of Chlorine is permanent while that of sulphur di oxide is temporary? Hypochlorous acid is unstable, and it easily dissociates to form nascent oxygen. The bleaching action of sulphur di oxide is temporary because it involves the process of reduction.
Why chlorine is a powerful bleaching agent?
Explanation: Chlorine react with water to form Hypochlorous acid along with Hydrochloric acid,as Hypochlorous acid is very unstable,it release nascent oxygen along with hydrochloric acid ,these nascent oxygen is a powerful beaching agent,and responsible for the bleaching action in Cl2.
Why does chlorine act as a powerful bleaching agent?
Hint: Chlorine can act as a bleaching agent due to the nascent oxygen it can produce in the reaction with water. Basically, one Cl atom gets oxidised and the other gets reduced when chlorine gas reacts with water. Complete answer: Thus, it bleaches the material.
What is the sign for chlorine?
symbol Cl
Chlorine is a chemical element with symbol Cl and atomic number 17.
Which of the following is used in preparation of chlorine?
Chlorine can be prepared in the laboratory by taking conc. Hydrochloric acid with manganese dioxide. The reaction of conc. Hydrochloric acid with manganese dioxide gives manganese di chloride, chlorine gas and water.
Is bleaching action of chlorine is permanent?
Chlorine is a strong oxidising and bleaching agent because of the nascent oxygen. Therefore, bleaching of chlorine is permanent.
Why bleaching action of Cl2 is permanent but so2 is temporary?
The p-Block Elements. Bleaching of flowers by Cl2 is permanent, while by SO2 it is temporary. When Chlorine react with water it form nascent oxygen which act as oxidising agent.
Is chlorine a bleach?
Myth #1: Bleach contains free-standing chlorine. There is no free-standing, or elemental, chlorine in bleach. Bleach is manufactured from salt and water to produce sodium hypochlorite, the active ingredient in bleach. Bleach is simply a water solution of this compound.
What is meant by bleaching action?
The bleaching action of Chlorine is permanent because it involves the process of oxidation. Chlorine reacts with water to produce nascent oxygen. This oxygen combines with the colours material and makes it colourless. It a powerful oxidising agent.
Which is powerful bleaching agent?
Chlorine water is strong bleaching agent.
How is chlorine used in everyday life?
Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water. It is also used to make hundreds of consumer products from paper to paints, and from textiles to insecticides. Another major use for chlorine is in organic chemistry.
What are the uses of chlorine?
Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water. It is also used to make hundreds of consumer products from paper to paints, and from textiles to insecticides.
Which of the following is used to prepare chlorine at room temperature?
Cr2O3.
Why bleaching action of chlorine is permanent but so2 is temporary?
Bleaching action of chlorine is based on oxidation while that of sulphur is based on reduction. Sulphur dioxide removes oxygen from the coloured substance and makes it colourless. But atmospheric oxygen slowly takes place of the removed oxygen and because of which the material regains the colour.
Which is not used for permanent bleaching?
Bleaching Powder is CaOCl2, it bleaches by nascent Chlorine,which is a strong bleaching agent. It has a permanent bleaching action, thus it is not used on silk – a natural fibre.
