Why conjugate base of strong acid is weak?
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.
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.
Hence, H2 is a very weak acid..
Is OH and acid or base?
The strong acid hydrogen chloride (HCl) is one example. If one of the ions is OH-, the solution is basic. An example of a strong base is sodium hydroxide (NaOH). There are other ions that make acidic and basic solutions, but we won’t be talking about them here.
Is c2h5oh an acid or base?
(i) Ethanol (C2H5OH) is not a base. … (i) Ethanol is not a base because it is not example of an organic compound, which have acidic nature. It does not give OH- ions in the solution. (ii) Ionisation When acid is added to water, the molecules of acid dissociate to form ions.
What is the conjugate base of Oh?
When acid give H+ then the remaining of its part is called conjugate base. So if we remove H+ from OH- ,we get O2-. Hence O2- is the conjugate base of OH-.
For what acid is hco3 − the conjugate base?
Bicarbonate: HCO3 – is known as hydrogen carbonate or bicarbonate. It’s a polyatomic ion that can bond to any positive ion. According to the Brønsted-Lowry theory of acids and bases, bicarbonate is a conjugate acid. The conjugate base of HCO3 – is CO3 -2, which is the carbonate ion.
Is hno3 a base or acid?
If you see any other acid or base than one of these strong ones it will be a weak acid or base (unless I specifically say otherwise in the problem). The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only).
What is the conjugate base for hso4?
HSO4- is a base since it has the ability to accept a proton but it is a conjugate base to H2SO4 since it is formed by the H2SO4 after donating a proton. The conjugate base of HSO4- is SO4 (2-), if that’s the question that you are asking.
Which acid has the weakest conjugate base?
Thus, HF (the strongest acid) has the weakest conjugate base (F-).
Is water an acid or base?
Water acts as an acid (donates H+) when it reacts with a stronger base, say sodium hydroxide. Water acts as a base (accepts H+) when it reacts with a stronger acid, say hydrochloric acid. If the medium is water, water, having a pH of 7, is considered neutral.
Is nh4+ A conjugate acid or base?
NH3 and NH4+ are a conjugate acid-base pair. NH4+ is the conjugate acid of the base NH3. Every acid has a conjugate base, and every base has a conjugate acid.
Is ch3coo an acid or base?
CH3COOH is a weak acid and dissociates partially in solution (as indicated with reversible arrow) to form H+ and CH3COO- ions. Since this is a reversible process, CH3COO- can accept H+ to form back CH3COOH. Therefore the nature of CH3COO- is basic and we call CH3COO- the conjugate base of CH3COOH.
Is HS an acid or base?

Why can’t nh4 be a base?
NH4+ is acidic according to Bronsted-Lowry Theory because it can give away one proton to other species (like water or hydroxide ion). However, it is neither acidic nor basic according to Lewis Theory because it doesn’t have any room to receive electron pairs and doesn’t have any lone electron pairs ti donate.
Which species is the conjugate base of an ammonium ion nh4+?
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.
