Question

among the following the pair which undergoes Displacement reaction is.

a) NaCl solution &Cu metal b) AgNo3 solution &Cu metal

c) MgCl2 solution &Al metal d) FeSo4 solution & ag metal​

Answer 1

Answer:

hey mate here is your answer

Explanation:

AgNo3 solution and Cu metal shows displacement reaction

mark me as brainiest!!!!!

Answer 2

$\huge\sf\pink{Answer}$

✭ As per the reactivity series of metals, copper is less reactive than sodium.Therefore, no displacement reaction will occur between NaCl solution and copper metal.

✭ Now, aluminium is less reactive than Magnesium, so no displacement reaction will occur between MgCl₂ solution and aluminium metal.

✭ Now, silver metal is less reactive than iron, so no displacement reaction will occur between FeSO₄ solution and Ag.

✭ Finally, displacement reaction will take place and Cu will displace Ag from its solution. This happens because copper metal is more reactive than silver.
