Define single displacement reaction? |
|
Answer» A single displacement reaction which is also called as single replacement reaction is a kind of oxidation-reduction chemical reaction when an ion or element moves out of a compound, i.e., one element is replaced by the other in a compound.\tWhen chlorine is added as a gas or gas dissolved in water to the solution of sodium bromide, the chlorine acquires the place of bromine. Since chlorine is more reactive than bromine, it displaces bromine from sodium bromide, and the solutions turn blue. The brown color is the bromine that is displaced.If you notice the equation, you can see that the Cl and Br have swapped their original places.\tchlorine + sodium bromide → sodium chloride + bromine\tCl2(aq) + 2NaBr(aq) → 2NaCl(aq) + Br2(aq)\t Welcome ayush...
