Question

1. \[\ce{AgNO3 + NaCl -> NaNO3 + AgCl}\]
2. \[\ce{K2SO4 + BaCl2 -> BaSO4 + 2KCl}\]

Which of the following options clearly describes both the reactions?

विकल्प

• (i) is double displacement, (ii) is displacement reaction.

• Both, (i) and (ii) are displacement reactions and precipitation reactions.

• Both, (i) and (ii) are double displacement reactions and precipitation reactions.

• (i) is displacement, (ii) is double displacement reaction.

Answer 1

Both, (i) and (ii) are double displacement reactions and precipitation reactions.

Explanation:

In both reactions, ions are exchanged between compounds, so they are double displacement reactions. Also, AgCl and BaSO₄ are insoluble solids formed, so both are precipitation reactions.
