Hint: Generally highly reactive chemicals react with the other chemicals and replace the less reactive chemicals from it. Chlorine is a greenish yellow color gas at room temperature. Aqueous potassium iodide means potassium iodide is present in water in soluble form.
Complete answer:
- In the question it is given that chlorine gas is passed in an aqueous potassium iodide solution to form potassium chloride and solid iodine.
- We have to identify which type of reaction it is.
- First we have to write the chemical reaction for it.
- The chemical reaction of chlorine gas with aqueous potassium iodide is as follows.
\[C{{l}_{2}}(g)+2KI(aq)\to 2KCl+{{I}_{2}}(s)\]
- In the above chemical reaction one mole of chlorine gas reacts with two moles of potassium iodide and forms two moles of potassium chloride and one mole of solid iodine as the products.
- We can see clearly that the highly reactive chlorine replaces the less reactive iodine from potassium iodide and forms potassium chloride.
- This type of reaction is called Displacement reaction.
- Therefore chlorine displaces the iodine in potassium iodide and forms potassium chloride and solid iodine and it is an example of displacement reaction.
So, the correct option is C.
Note:
Potassium chloride is a white color salt and it is odorless and crystalline in nature. Potassium chloride is soluble in water. Before the displacement reaction chlorine is a gas but after the displacement reaction chlorine is present in combined form with potassium in solid form.
