Which one of the following Would the following result in a displacement reaction?
|
|
Iron with magnesium chloride
|
|
|
magnesium with iron chloride
|
|
|
Iron with Zinc Sulphate
|
|
|
gold with silver nitrate
|
Explanation:
Detailed explanation-1: -AgNO3 solution and copper metal will give displacement reaction where copper being more reactive than silver, displaces it from silver nitrate.
Detailed explanation-2: -Iron displaces copper ions from an aqueous solution of copper sulphate. It is a single displacement reaction of one metal by another metal. Iron is placed above copper in the activity series. Elements placed above in this series are more reactive than those placed below them.
Detailed explanation-3: -Magnesium can displace iron from ferrous sulphate solution, but iron cannot displace magnesium from magnesium sulphate solution.
