Which Acid Has The Strongest Conjugate Base In Aqueous Solution?

Which of the following bases has the strongest conjugate acid?

Answer and Explanation: Of the given acids, HClO is the strongest conjugate base.

This is why because, despite being a weak acid, HClO tends to lose the hydrogen easily…..

What is the formula for the strongest conjugate base?

In this example, the order of strongest conjugate bases from weakest to strongest would be F-, HCOOH, CH3COOH, HClO, I-. Therefore the acid that produces the strongest conjugate base would be HIO.

What is the conjugate base for nh4+?

1 Answer. The conjugate base of ammonium ion, NH+4 , is ammonia, NH3 ………….

What is the conjugate 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. In water it loses its acidic hydrogen to the water molecule as H+ ion.

How do you determine the strongest acid in an aqueous solution?

If the acid is 100 percent dissociated in solutions of 1.0 M or less, it is called strong….You should commit the strong acids to memory:HCl: hydrochloric acid.HNO3: nitric acid.H2SO4: sulfuric acid.HBr: hydrobromic acid.HI: hydroiodic acid.HClO4: perchloric acid.

Is the conjugate base of a strong acid weak?

The more stable the conjugate base, the stronger the acid. A stable conjugate base is not very basic. A very strong acid has a very weak conjugate base and a very weak acid has a very strong conjugate base.

What are the 7 strong acids?

There are 7 strong acids: chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid. Being part of the list of strong acids doesn’t give any indication of how dangerous or damaging an acid is though.

Which acid has the strongest conjugate base quizlet?

therefore C5H5NH+ is the strongest conjugate acid.

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.

Is Hi a strong acid?

HCl, HBr, and HI are all strong acids, whereas HF is a weak acid. The acid strength increases as the experimental pKa values decrease in the following order: … Hydrochloric acid: Hydrochloric acid is a clear, colorless solution of hydrogen chloride (HCl) in water.

Is h2so4 a strong acid?

Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H3O+) and hydrogen sulfate ions (HSO4−). In dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and sulfate ions (SO42−).

Which of the following is the strongest acid in aqueous solution?

The strongest acid that can exist in aqueous solutions is H3O+. The strongest base that can exist in aqueous solutions is OH-. In the reaction between ammonia, NH3 and water, ammonia is a base that accepts a proton from water to form the ammonium ion, NH4+, its conjugate acid.

Is BA OH 2 a strong base?

YES. Barium hydroxide is a strong base such as NaOH, KOH. Barium hydroxide is a group IIA metal hydroxide and it dissolves very well in water to give a strong base solution such as group IA metals hydroxides. Barium hydroxide dissociates completely in water to give barium ions and hydroxyl ions.

How do you know if a conjugate base is strong?

There is a relationship between the strength of an acid (or base) and the strength of its conjugate base (or conjugate acid): ⚛ The stronger the acid, the weaker its conjugate base. ⚛ The weaker the acid, the stronger its conjugate base. ⚛ The stronger the base, the weaker its conjugate acid.

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 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–,

How do you know which conjugate base is most stable?

pKa is similar to pH in that low (and even negative values) denote strong acids. That’s because pKa is based on the equilibrium: According to this, anything which stabilizes the conjugate base will increase the acidity. Therefore pKa is also a measure of how stable the conjugate base is.

Which is the conjugate base?

Conjugate Base Definition A more general definition is that a conjugate base is the base member, X-, of a pair of compounds that transform into each other by gaining or losing a proton. The conjugate base is able to gain or absorb a proton in a chemical reaction.
