Question

Ammonia (NH3) Is base.

How best do you describe Ammonia when dissolved in water

B. Ammonia forms a neutral solution.

C. Ammonia forms a buffered solution.

d. Ammonia acts as base because has OH- and makes water accepts hydrogen.

Answer 1

Ammonia accepts a proton from water

Step-by-step explanation:

Let us quickly remind ourselves of the Brownstead-Lowry definition of an acid. According to Brownstd-Lowry, an acid is any substance that donates hydrogen ions while a base is any substance that accepts hydrogen ions. The hydrogen ion is also known as a proton.

If we look at the behaviour of ammonia in water;

NH3(g) + H2O(l) ----> NH4^+(aq) + OH^-(aq)

We can easily see that ammonia accepts a proton from water (this makes it a Brownstd-Lowry base) and the hydroxide ion is formed in the process. Water functions as the proton donor here.
