Example of single displacement reaction
Answers
All simple metal with acid reactions are single displacement reactions. For example, the reaction between magnesium, Mg, and hydrochloric acid, HCl, forms magnesium chloride, MgCl2, and hydrogen, H2.
Single Displacement Reactions
Single displacement reactions are reactions where one reactant replaces part of the other.
AB + C → AC + B
An example is the reaction between iron and copper sulfate to produce iron sulfate and copper:
Fe + CuSO4 → FeSO4 + Cu
Here, both iron and copper have the same valence. One metal cation takes the place of the other bonding to the sulfate anion.
Double Displacement Reactions
Double displacement reactions are reactions where the cations and anions in the reactants switch partners to form products.
AB + CD → AD + CB
An example is the reaction between silver nitrate and sodium chloride to form silver chloride and sodium nitrate:
AgNO3 + NaCl → AgCl + NaNO3
