Assertion and reason question Assertion: pH of ammonium nitrate solution is less than 7 Reason: salts of weak bases and strong acid is acidic
Answers
Answer:
if both assertion and reason are true and reason is the correct explanation of the assertion
Answer:
The Assertion and the Reason both given here are true as well as reason justifies the assertion statement. Hence, correct answer would be both assertion and reason are true.
Explanation:
Ammonium Nitrate is a salt which is denoted by formula NH₄NO₃. It is formed by neutralization reaction between a base which is Ammonium(NH₄⁺) and an acid which is Nitrate ion(NO₃⁻).
Ammonium(NH₄⁺) is a weak base and Nitrate ion(NO₃⁻) is a strongly acidic in nature. Now, when there is a neutralization reaction between a weak base and a strong acid, the salt formed is always acidic in aqueous solution because of majority of negative ions.
Therefore, accordingly, NH₄NO₃ will be acidic in aqueous solution.
