What is the conjugate base for hno2?
This is the forward reaction; in the reverse reaction, NO−2 is now the Brønsted-Lowry base (conjugate of HNO2 ) because it accepts a proton from hydronium (conjugate acid of H2O ) to form nitrous acid again..
Which is more dangerous acid or base?
Explanation: Acids and bases have various strengths, all depending on their pH . An extremely strong base would be more dangerous than a weak acid, and vice versa.
What are the 7 strong bases?
Some common strong Arrhenius bases include:Potassium hydroxide (KOH)Sodium hydroxide (NaOH)Barium hydroxide (Ba(OH)2)Caesium hydroxide (CsOH)Strontium hydroxide (Sr(OH)2)Calcium hydroxide (Ca(OH)2)Lithium hydroxide (LiOH)Rubidium hydroxide (RbOH)
Which is the most strong acid?
None of the strong acids traditionally listed in a chemistry text holds the title of World’s Strongest Acid. The record-holder used to be fluorosulfuric acid (HFSO3), but the carborane superacids are hundreds of times stronger than fluorosulfuric acid and over a million times stronger than concentrated sulfuric acid.
Is nh4+ an acid or base?
NH4+, aka ammonium ion, is for all practical purposes an acid. It readily “gives off” a proton in the form of h+. NH4+ is the conjugate acid of the base, NH3, aka ammonia.
What is the conjugate base of HF?

What acid has the strongest conjugate base?
In general, the stronger the acid, the weaker its conjugate base. Likewise, the weaker the acid, the stronger its conjugate base….Strong and Weak Acids and Acid Ionization Constant.AcidConjugate BaseHCl (hydrochloric acid) (strongest)Cl− (chloride ion) (weakest)H2SO4 (sulfuric acid)HSO4− (hydrogen sulfate ion)7 more rows•Jun 26, 2013
How do you know if a base is strong?
The issue is similar with bases: a strong base is a base that is 100% ionized in solution. If it is less than 100% ionized in solution, it is a weak base. There are very few strong bases (see Table 12.2 “Strong Acids and Bases”); any base not listed is a weak base. All strong bases are OH – compounds.

Does a strong acid have a strong conjugate base?
Strong acids have a weak conjugate base. Example: HCl is a strong acid. If HCl is a strong acid, it must be a good proton donor. … Thus, the Cl- ion must be a weak base.
What is the conjugate of a weak base?
The conjugate acid of a weak base is a strong acid. Footnotes: 1. The terms “acid” and “base” refer to a Brønsted-Lowry acid and a Brønsted-Lowry base.
Is ClO a weak base?
What reaction is taking place? NaClO is a salt, which will dissolve completely in water, to form Na+ and ClO-. This second species, hypochlorite, ClO-, is the conjugate base of the weak acid, HClO. So, this is a weak base equilibrium problem, like the previous example.
What makes a base stronger?
These are very much weaker bases than ammonia. Two of the factors which influence the strength of a base are: the ease with which the lone pair picks up a hydrogen ion, the stability of the ions being formed.
What does conjugate base mean?
Conjugate Base Definition When an acid dissociates into its ions in water, it loses a hydrogen ion. The species that is formed is the acid’s conjugate base. … The conjugate base is able to gain or absorb a proton in a chemical reaction. The conjugate acid donates the proton or hydrogen in the reaction.
Which has the strongest base?
Ortho-diethynylbenzene dianion is a Superbase with the chemical formula of [C6H4(C2)2]2-. The base was created in mass spectroscopy experiments by researchers in Australia. This base is reportedly the strongest superbase, with a proton affinity of 1843 kJ mol−1.
What is the formula for the weakest conjugate base?
:- as the strong acid has high tendency to lose proton its conjugate base will be unstable on accepting proton so it will be the weakest conjugate base.Example HSO4–,
Why conjugate base of weak acid is strong?
A strong acid like HCl donates its proton so readily that there is essentially no tendency for the conjugate base Cl– to reaccept a proton. Consequently, Cl– is a very weak base. A strong base like the H– ion accepts a proton and holds it so firmly that there is no tendency for the conjugate acid H2 to donate a proton.
