Question

Which of the following pair of compounds undergo displacement reaction when they react with each other?

• A. $\text{Cu and NaCl solution}$
• B. $\text{Mg and NaCl solution}$
• C. $\text{Ag and}{\text{FeSO}}_4\text{solution}$
• D. ${\text{Cu and AgNO}}_3\text{solution}$

Answer 1

The correct option is D ${\text{Cu and AgNO}}_3\text{solution}$

Silver nitrate and copper metal undergoes displacement reaction as copper is more reactive than silver. Hence, it displaces silver to form copper nitrate.

$\text{Cu(s)}+2{\text{AgNO}}_3\text{(aq)}\to {Cu\left(N{O}_3\right)}_2\text{(aq)}+2\text{Ag(s)}$
