Question

Give an example of a double displacement reaction other than the one given in Activity 1.10​

Answer 1

Answer:

Reaction Between silver nitrate (AgNO3) and Sodium chloride (NaCl) is an example of double displacement reaction. During the reaction negative and positive ions trade positions as a result in the formation of white silver chloride precipitate. The chemical reaction is given below.

Ag+ + NO3– + Na+ + Cl– → AgCl + Na+ + NO3–

Answer 2

Answer:

AgNO3 + NaCl → AgCl + NaNO3

BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2 NaCl(aq)

Na2 S+2HCl→2NaCl+H2S
