What happens when hydrogen sulphide is passed through chlorine gas?
If chlorine is passed through a solution of hydrogen sulphide in water, the solution turns turbid due to the formation of. H2S+Cl2water→2HCl+S Due to formation of free sulphur the solution becomes turbid.
What is the reaction between chlorine and hydrogen?
When hydrogen reacts with chlorine, hydrogen chloride is formed. Hydrogen chloride is a gas, and has the formula HCl(g). When hydrogen chloride dissolves in water, hydrochloric acid is formed.
Why the reaction of chlorine with hydrogen sulphide is deemed a redox reaction?
Give reason why the reaction of chlorine with hydrogen sulphide is deemed a redox reaction? Chlorine gets reduced to HCl and H2S is oxidised, hence it is a redox reaction.
Why does chlorine show bleaching action?
This is an oxidation process. When chlorine reacts with water, it produces nascent oxygen. This nascent oxygen combines with colored substances present in organic matter, and oxidizes it to colorless substances. Bleaching action of chlorine is permanent because it involves the oxidation process.
What is the formula of hydrogen chlorine?
The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colourless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry.
What is HCL formula?
What happens when hydrogen sulphide reacts with copper sulphate?
When hydrogen sulphide gas is passed through a blue solution of copper sulphate, a black precipitate of copper sulphide is obtained and the sulphuric acid so formed remains in the solution. In this reaction, cupric ions (from copper sulphate) combine with sulphide ions (from hydrogen sulfide) to form cupric sulphide.
What are uses of chlorine?
Chlorine has a variety of uses. It is used to disinfect water and is part of the sanitation process for sewage and industrial waste. During the production of paper and cloth, chlorine is used as a bleaching agent. It is also used in cleaning products, including household bleach which is chlorine dissolved in water.
How does h2o2 act as bleaching agent?
H2O2 or hydrogen peroxide acts as a strong oxidizing agent both in acidic and basic media. When added to a cloth, it breaks the chemical bonds of the chromophores (colour producing agents). Hence, the visible light is not absorbed and the cloth gets whitened.
Why is chlorine the strongest 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.
What is the combination of reaction?
A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product). Such reactions are represented by equations of the following form: X + Y → XY (A+B → AB).
Why is H2 not h?
Because the hydrogen atoms are covalently bonded together they form a molecule; so H2 is also referred to as molecular hydrogen. The hydrogen molecule contains two protons and two electrons making it a neutrally-charged molecule.
How does chlorine react with hydrogen sulfide in aqueous solution?
Chlorine reacts with hydrogen sulfide in aqueous solution Cl2 (aq) + H2S(aq)→ S(s) + 2 H* (aq) + 2 Cl¯(aq) in a second-order reaction that follows the rate expression rate = k[Cl, ][H2S] %3D Which, if any, of the following mechanisms are consistent with the observed rate expression?
Why does chlorine neutralize the smell of hydrogen sulfide?
One benefit of this odor is that it makes hydrogen sulfide detectable in concentrations far below the toxic level. The most common source of hydrogen sulfide is anaerobic bacteria that produce hydrogen sulfide as a waste product. The use of chlorine is a common method of neutralizing the hydrogen sulfide in well water.
What is the reaction between H2S and Cl2?
H2S(gas)+ Cl2(gas) have a redox reaction, S (sulfur) drops out ( solid) and 2HCl (g) is formed. Cl2 is the oxidiser and get it self reduced to HCl.
Why does hydrogen sulphide act as a reducing agent?
(d) Hydrogen sulphide acts as the reducing agent because it causes chlorine to be reduced. Many redox reactions do not involve oxygen or hydrogen. These reactions can be explained based on the transfer of electrons that occurred. Oxidation is a loss of electrons and reduction is a gain of electrons.
