Assertion Ammonia is a base. Reason Ammonia when dissolved in water takes up proton to form ammonium and furnishes \( \boldsymbol{O H}^{-} \) ions.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
According to the Brønsted-Lowry theory, a base is a proton acceptor. Ammonia (NH₃) accepts a proton (H⁺) from water, forming ammonium (NH₄⁺) and hydroxide (OH⁻) ions. This directly explains why ammonia is a base. Therefore, the assertion is correct, and the reason correctly explains it.
