Quick Answer: What Is The Conjugate Base Of HF?

What is the conjugate base for HF in h2o?

In the reaction above HF is the acid and H2O is the base.

The HF has given a proton to the H2O, forming H3O+ and F–.

Since the product H3O+ can donate a proton back to F– it is labeled the conjugate acid, while the F– is the conjugate base..

Which acid has the strongest conjugate base?

hydrochloric acidIn 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

Is the conjugate base of a strong acid weak?

Strong acids have a weak conjugate base. Thus, the Cl- ion must be a weak base. Strong bases have a weak conjugate acid.

Which is weakest acid?

hydrofluoric acidThe only weak acid formed by the reaction between hydrogen and a halogen is hydrofluoric acid (HF). While technically a weak acid, hydrofluoric acid is extremely powerful and highly corrosive.

Is BA OH 2 a strong base?

YES. Barium hydroxide is a strong base such as NaOH, KOH. … Barium hydroxide dissociates completely in water to give barium ions and hydroxyl ions.

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–,

What is the conjugate base of ch3cooh?

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.

What is the conjugate base of ho -?

Water (H2O) is the conjugate acid of hydroxide (HO-). To make the conjugate acid of any base, just add an H+. Comment on awemond’s post “Water (H2O) is the conjugate acid of hydroxide (HO…”

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. 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.

Is ch3coo a Lewis base?

Acid-bases occur as conjugate acid-base pairs. CH3COOH and CH3COO- are a pair. … Ammonia is the Lewis base. It donates lone-pair electrons to BF3, the Lewis acid and the electron acceptor.
