Answer:
Na₂SO4 (aq) +BaCl₂(aq)
2NaCl(
aq)
When a solution of hydrochloric acid is added to a solution of lead nitrate, a white precipitate of lead chloride is formed.
Pb(NO3)2(aq) + 2HCl(aq)
+ 2HNO3(aq)
Lead nitrate Lead chloride Pb+ ions from lead nitrate combine with 2Cl ions from hydrochloric acid and a precipitate of lead chloride is formed. Thus, there is an exchange of ions between the two reactants i.e, lead nitrate and hydrochloric acid, and thus this reaction is a double displacement reaction.
