Hint: Chlorine is basically a chemical element which is yellowish in colour. It is a reactive element and is also a strong oxidising agent. When chlorine is added to water, it dissolves to form a solution called chlorine water.
Complete step by step answer:
- First of all let’s see the reaction that takes place when we add chlorine in water:
\[C{{l}_{2}}+{{H}_{2}}O\to HCl+HOCl\]
Here we can see that the products formed are HCl and HOCl. Due to which yellow colour of Chlorine water fades because of
- HOCl is a compound which is formed, will further dissociate into HCl and [O].
- [O] is the nascent oxygen, which is responsible for the bleaching action.
- Hence, we can conclude that the correct option is (A), that is the yellow colour of Chlorine water fades because of the formation of HCl and HOCl.
Additional information:
- It is found that water chlorination is an important process used nowadays. In this process chlorine is added to water. This method is very much effective in killing bacteria, various viruses and all the other microbes present in water.
- We can say that it is basically used to prevent the spread of the waterborne diseases like typhoid, cholera and dysentery.
- It is also found that depending on the pH conditions, different chlorine containing substances are used. There are three most common types of chlorine used in the treatment of water like: calcium hypochlorite, sodium hypochlorite and chlorine gas.
Note:
- Chlorine is widely used as a disinfectant. And it is the third most abundant element on earth.
- Chlorine water is found to cause several skin problems like skin rashes, and irritation of skin when used in excess in the process of chlorination.
