Which of the following statements is true concerning an aqueous solution of the weak base nh3?
a. oh– is a stronger base than nh3.
b. nh3 is a weaker base than h2o.
c. oh– is a stronger acid than nh4+.
d. h2o is a stronger acid than h3o+.
e. nh4+ is a stronger acid than h3o+.

Option (A) is the correct answer.

Explanation:

When weak base is dissolved in water then the reaction will be as follows.

When is compared with water then oxygen atom of being more electronegative in nature will keep its lone pair of electrons towards itself.

Hence, water will act as a neutral molecule and hence, will act as a stronger base as compared to .

On the other hand, will have both lone pair of electrons and a negative charge. Hence, its electron density is much more as compared to that only contains a lone pair of electron.

Therefore, will act as a weak base as compared to .

Thus, we can conclude that the statement is a stronger base than , is true concerning an aqueous solution of the weak base .
