Quick Answer: What Is The Formula For The Strongest Conjugate Base?

Which is a stronger base no2 or no3?

NO3- has 3 resonance structures while NO2- only has 2.

This is significant because the electrons can delocalize over a greater volume that allows for more stabilization of the negative charge.

Since NO3- can hold the negative charge better than NO2-, NO3- is a more stable conjugate base..

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–,

Which is the stronger brønsted Lowry base HS − or HSO − 4?

(c)H2SO4 is a stronger acid than H2S, so HS- is the stronger conjugate base. (d) H2S is a stronger acid than H2SO4, so HSO4- is the stronger conjugate base. (e) Since H2S is one of the seven strong acids, HS- is a negligible base.

What is the conjugate base of HF?

Is ClO a weak base?

In this reaction, OH- is the strongest base. … 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.

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.

Is clo4 an acid or base?

Perchlorate is a monovalent inorganic anion obtained by deprotonation of perchloric acid. It is a monovalent inorganic anion and a chlorine oxoanion. It is a conjugate base of a perchloric acid.

What makes a base stronger?

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: substance formed when an acid loses a hydrogen ion. Considered a base because it can gain a hydrogen ion to reform the acid.

Is LiOH a weak base?

LiOH is a weak base because it is more covalent due to small size. … Hydroxides of all alkali metals are strong base but LiOH is least basic because the dissociation of LiOH is minimum in water.As LiOH is having maxmium covalent character because of Fajans’ Rule.

WHY IS F a weak base?

It is a weak base because F is a most electroneagtive elements which has more affection towards electron and it will never donates electron to other so it is a weak base.

Is nh4+ an acid or base?

NH3 and NH4+ are a conjugate acid-base pair. NH4+ is the conjugate acid of the base NH3.

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.

What is the conjugate base for hno2?

The ‘Conjugate Base’ is the Chloride anion (Cl−) which has the potential of functioning as a proton acceptor. However neither the H−OHorCl− have strong enough electrostatic properties to interact in a proton transfer process of transferring the Hydrogen back to the Hydroxide ion.

Which acid is the weakest?

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)HNO3 (nitric acid)NO3− (nitrate ion)Weak Acids5 more rows•Jun 26, 2013

What is the conjugate base of a weak acid?

The conjugate base of a weak acid is usually a strong base. The conjugate base of an acid is the anion that results when the acid molecule loses its hydrogen to a base. Acetic acid (CH3COOH) is a weak acid.
