Question

Assertion: Copper does not reacts with dilute sulphuric acid Reason: Copper is more reactive than hydrogen a) Both Assertion and Reason are correct and the Reason is the correct explanation of the assertion. b) The Assertion and Reason are correct but the Reason is not the correct explanation of the Assertion. c) The Assertion is true but the Reason is wrong d) The statement of the Assertion is false but the Reason is true i will follow if your answer is correct I know the answer

Answer 1

Answer:

Sulperic acid reason is because copper is a property of element of very large amounts of water so it is dilute Sulperic acid is not react

Answer 2

$\large{\underline{\underline{\red{\tt{Assertion:-}}}}}$

• Copper does not reacts with dilute sulphuric acid .

$\large{\underline{\underline{\red{\tt{Reason:-}}}}}$

• Copper is more reactive than hydrogen.

$\large{\underline{\underline{\red{\tt{Explanation:-}}}}}$

Now in Assertion its given that copper does not react with dilute sulphuric acid but in the reason it is given that copper is more reactive than hydrogen but this is not possible as the less reactive cannot displace the more reactive element from its salt solution.

We know that Copper (Cu) is located below Hydrogen (H) so , copper is less reactive than Hydrogen .

Hence here Assertion is true but Reason is wrong .

So the correct option would be " The assertion is right but the reason is wrong." [c]

$\large{\underline{\green{\tt{\dag Displacement\:Reac^n:-}}}}$

$\bullet$ The reacⁿ in which a more reactive element displaces a less reactive element from its salt solⁿ is called a displacement reacⁿ.

$\bullet$ For this we have a reactivity series in which the element located at the top can displace elements below them from their salt solⁿ.

Let us understand with the help of an example for things to be more clear.

♠ Reacⁿ of Iron and Copper Sulphate solution:

When a iron nail is placed in the copper sulphate solⁿ , iron displaces copper from its salt solution and forms ferrous sulphate.the original colour of the solution was blue but it changes to green in colour after the reaction. a black coating can be also seen on the iron nail.

All this all these changes indicate a chemical reaction.
