Assertion : When zinc is added to dilute hydrochloric acid, hydrogen is given off.


Reason : Hydrogen chloride molecules contain hydrochloric acid and hydrogen atoms.

  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

  • b)
    Assertion (A) is true but reason (R) is false.

  • c)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

  • d)
    Assertion (A) is false but reason (R) is true.

The correct answer is b) Assertion (A) is true but reason (R) is false.


Explanation:




  • Assertion (A): When zinc is added to dilute hydrochloric acid, hydrogen is indeed given off. This is a chemical reaction where zinc displaces hydrogen from hydrochloric acid, producing zinc chloride and hydrogen gas.



  • Reason (R): The statement that "Hydrogen chloride molecules contain hydrochloric acid and hydrogen atoms" is misleading. Hydrogen chloride (HCl) is a compound consisting of hydrogen and chlorine, but it doesn't accurately explain why hydrogen gas is evolved when zinc reacts with dilute HCl.




Therefore, the assertion is true, but the reason does not correctly explain it.

Assertion and Reasoning in Chemistry

Assertion: A statement that is considered to be true or false on the basis of experimental evidence or logical deduction.

Reasoning: A statement that provides an explanation or justification for an assertion.

Explanation:

• The assertion states that when zinc is added to dilute hydrochloric acid, hydrogen gas is given off.

• This is because zinc reacts with hydrochloric acid to form zinc chloride and hydrogen gas.

Zn + 2HCl → ZnCl2 + H2

• The reasoning behind this assertion is that hydrochloric acid molecules contain hydrogen atoms that are released when the acid reacts with zinc.

• The hydrogen atoms combine to form hydrogen gas, which is given off as a product of the reaction.

• Therefore, both the assertion and reasoning are true, but the reasoning is not the correct explanation for the assertion.

• The correct explanation is that the reaction between zinc and hydrochloric acid releases hydrogen gas as a product.

• Hence, the correct option is B - Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
