Which one of the following is not correctly matched in the term of Acid forming fertilizers and Acid equivalent?

A. Ammonium chloride ⇔ 128

B. Urea ⇔ 60

C. ASN ⇔ 93

D. Ammonium sulphate ⇔ 110

Answer: Option B

Solution(By Examveda Team)

Acid forming fertilizers are acidifying agents which can help to raise the acidity levels of the soil. And Acid equivalent is that portion of a formulation that theoretically could be converted back to the corresponding parent acid.
The acid equivalent of urea is 80, not 60.
