Question

NH3 is a weak alkali that does not dissociate fully into its solution. Which of the following is true about NH3?

A. It has a very low pH.
B. It's dissociation is a reversible reaction.
C. It has a high H+ concentration.
D. It will release all of its OH- ions.

Answer 1

Answer:

B. It's dissociation is a reversible reaction

Step-by-step explanation:

NH3 is a weak alkali that does not dissociate fully into its solution. Only parts of the ammonia takes part in the dissociation process.

NH3 + H20 —> NH4+ + OH-

This dissociation is reversible which means the reactants can be formed from the product gotten from the dissociation

It has a high pH due to its basic nature. It also has a Low concentration of H+ ions and not all the OH- ions are released.
