# conjugate base of ammonium

Is it possible to know the pKa of a certain conjugated base, if all you're given is the pKa of the acid? Ammonia: NH 3: 36: Amide: Acetylene (ethyne) C 2 H 2: 26: Acetylide: Ethanol: C 2 H 5 OH: 16: Ethoxide: Water: HOH: 15.7: Hydroxide: Ammonium: NH 4 + H—NH 3: 9.8: NH 3: Ammonia: Hydroflouric acid: HF: 4: Flouride : Use this table to predict which conjugate base will favorably react with which conjugate acids. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Favorite Answer. What is the conflict of the story of sinigang? @HydrousCaperilla actually if I understand your question, the phrase "stronger conjugate base" does not actually mean stronger than the weaker acid. Does Jerry Seinfeld have Parkinson's disease? A weaker base has a stronger conjugate acid, not necessarily a totally strong one. How do smaller capacitors filter out higher frequencies than larger values? Were any IBM mainframes ever run multiuser? What is the benefit of having FIPS hardware-level encryption on a drive when you can use Veracrypt instead? The pK b of ammonia is 4.75. pK a = 14 – pK b. Is ammonium a strong or weak acid? I'd dare say most conjugate bases of weak acids mentioned in textbooks are weak ones. Ammonium, $\ce{NH_4^+}$, is the conjugate acid of ammonia, $\ce{NH_3}$. In that case, the convention that they're using is that the conjugate of a strong acid is too weak to be considered a base at all, but that a weak acid has a weak conjugate base (and the conjugate of a string base is too weak to be considered an acid). As a general rule, the conjugate base … In chemistry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases and Lewis bases.All definitions agree that bases are substances which react with acids as originally proposed by G.-F. Rouelle in the mid-18th century.. Arrhenius proposed in 1884 that a base is a substance which dissociates in aqueous solution to form hydroxide ions OH −. A weak acid like acetic acid with a p$K_{\rm a}$ of 4.76 will have a weak conjugate base with a p$K_{\rm b}$ of $14-4.76=9.24$. 'Conjugate' means ONE proton more (acid) or less (base) than the described acid or base respectively: So the conjugate acid of ammonia (NH3) is the ammonium cation NH4+. Use MathJax to format equations. Copyright © 2020 Multiply Media, LLC. So, ammonium ion is 0.65 M and 0.35 M remaining ammonia (base). If you are 13 years old when were you born?

When I write  quantitatively  I mean that there is enough difference in The definition of "strong" as having $pK$ below -1.7 may not be entirely true.
