Question

$StatementI-$ A reaction will occur when solid copper is placed into an aqueous solution of magnesium chloride.
$StatementII-$ Copper is higher on the activity series than magnesium.

• A. Statement $I$ is true, Statement $I$ is true
• B. Statement $I$ is true, Statement $I$ is false
• C. Statement $I$ is false, Statement $I$ is true
• D. Statement $I$ is false, Statement $II$ is false
• E. Statement $I$ is true, Statement $I$ is true and is a correct explanation of the phenomena described in $I$

Answer 1

The correct option is D Statement $I$ is false, Statement $II$ is false

The reactivity series is

$K>Na>Ca>Mg>Al>Ls>Fe>Cu$

i.e magnesium is higher on activity series than copper.

i.e. statement $II$ is wrong.

Statement $I$ is also wrong :

$Mg{Cl}_2+Cu⟶$ no reaction

as magnesium has higher reactivity than copper.
