Question

Assertion : Sodium displaces copper from its salt solution. Reason : Reactive metals can displace less reactive metals from their compounds in solution as molten form. (a) Both Assertion and Reason are true and Reason is the correct explanation of Assertion. (b) Both Assertion and Reason are true but Reason is not the correct explanation of Assertion. (c) Assertion is true but Reason is false. (d) Both Assertion and Reason are false.​

Answer 1

Answer:

Option(a)

Explanation:

When a reaction involves a reaction between a metal(of higher reactivity) and a metal compound(with metal of low reactivity), the highly reactive metal displaces the one with low reactivity. Here Sodium is Group1 Alkali metal which is highly reactive as its oxidation state is +1. So, Na displaces Cu from its salt solution due to Na's higher reactivity. The reason for the answer explains the assertion clearly, so option(a) is right

Answer 2

Answer:

Option A - Both assertion and reason are true and the reason is the correct explanation of the assertion.

Explanation:

Sodium is a highly reactive metal and is on the top in the reactivity series after potassium. Copper is less reactive than sodium.

Sodium displaces copper from  its salt solution because reactive metals can displace less  reactive metals from their compounds in  solution as molten form.
