15 мая 2016 г. · Both ammonia is a weak base and ammonium ion is a weak acid. Many, even most, acid/base conjugate pairs are like that.

28 дек. 2016 г. · It is a weak base because it is not a certainty that all the NHX3's in a given sample will pick up a proton and hold onto it. In any given ...

5 февр. 2017 г. · It means that conjugate base (ammonia) is really stable, which makes conjugate acid a strong acid.

25 сент. 2013 г. · Ammonia has a pKa value (a description what that means can be found in this answer of mine) of 33 and is thus not acidic at all - you'd need ...

20 июл. 2018 г. · Therefore the terminal alkynes are more acidic and have a lower pKa than ammonia.

26 апр. 2024 г. · Since NH+4 has donated an electron here, it behaves as an acid and ammonia is its product, hence ammonia is the conjugate base of NH+4 while H2 ...

16 дек. 2014 г. · Because the ammonium ion is more acidic than neutral water, very little NHX4X+ will be present at equilibrium. In contrast, the relevant pKa ...

18 нояб. 2014 г. · When it comes to comparing ammonia and water, the acidity or basicity can be explained because of the central atoms electronegativity.

11 мая 2014 г. · The bigger size of nitrogen decreases its positive charge density, making it less Coulombically favorable for ammonium ion to kick off a proton.

9 сент. 2014 г. · The first compound is more acidic. The ammonium functionality is inductively electron withdrawing, stabilizing the conjugate base (carboxylic ...
