what is chemical displacement reaction and activity series of elements.
Answers
Answer:
A displacement reaction happens when a more reactive metal (one that forms positive ions more easily) displaces a less reactive metal from a compound.
Explanation:
Magnesium is more reactive than copper, so magnesium can displace copper from a copper sulfate solution to create magnesium sulfate.
Magnesium + copper sulfate → magnesium sulfate + copper
Mg(s) + CuSO4(aq) → MgSO4(aq) + Cu(s)
Platinum, however, is less reactive than copper and so cannot displace copper from a copper sulfate solution.
Answer:
A metal can only displace another metal from a compound if it is located above it in the reactivity series. A displacement reaction happens when a more reactive metal (one that forms positive ions more easily) displaces a less reactive metal from a compound.
