The student of a class discusses acid base rule as follows.

Student- $1$ : A substance which donates a proton to other substance is an acid.
Student- $2$ : A substance which accepts a proton from other substance is base.
Student- $3$ : $O H^{-}$ ion is not formed in $N H_{3}$ ; therefore, it may not be a base.
Student- $4$ : $O H^{-}$ ion is not formed in $N H_{3}$ , then also it is a base.
