What is the conjugate base and acid of NH3?
Answers
Answer:
Use this table to predict which conjugate base will favorably react with which conjugate acids. Pay attention to the pKa values shown. As a general rule, the conjugate base of any acid will react with, and remove, the proton (H+ ion) from any conjugate acid that is stronger than the conjugate acid from which the conjugate base you are looking at was derived from.
In the chart above, the conjugate base will remove a proton from every conjugate acid that is below it in the table.
Examples:
The Amide ion will remove (quantitatively) a proton from Acetylene, Ethanol, Water, and Hydroflouric acid, these cells are shown in color above, so that the amide ion will remove a proton from the acids below it in this table (smaller pKa values, stronger acids).
The Hydroxide ion will remove (quantitatively) a proton only from Hydroflouric acid and the Ammonium ion.
The Ethenyl ion will remove (quantitatively) a proton from Ammonia, Acetylene, Ethanol, Water, and Hydroflouric acid.
The Methyl carbanion will remove (quantitatively) a proton from all acids (from Ethene, Ammonia, Acetylene, Ethanol, Water, and Hydroflouric Acid)
When I write — quantitatively — I mean that there is enough difference in the pKa values (of the conjugate acids) to remove greater than 99% of the protons from the acids below them. A difference of 2 pKa values will allow the conjugate base coming from the weaker acid will remove >99% of protons from the stronger acid.
