What are double displacement reactions

Asked by Nidhimalhotra888 | 6th Dec, 2019, 04:31: PM

Expert Answer:

Double displacement: This is when the anions and cations of two different molecules switch places, forming two entirely different compounds. These reactions are in the general form:

AB + CD → AD + CB

One example of a double displacement reaction is the reaction of lead (II) nitrate with potassium iodide to form lead (II) iodide and potassium nitrate:

Pb(NO3)2 + 2 KI  PbI2 + 2 KNO3

Reactions that can be classified as double displacements include precipitation reactions, neutralization reactions and gas forming reactions.
