Question

Define the following:-

(a) Displacement reaction
(b) Precipitation reaction​

Answer 1

Answer:

In a double displacement reaction, both ionic reactants dissociate in water and their ions bonds with the respective cation or anion from the other reactant. For a double displacement reaction to be a precipitation reaction, one of the resulting products must be insoluble in aqueous solution.
