## How do you know which conjugate base is stronger?

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.

## How do you tell if a conjugate base is strong or 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.

**How do you know if a conjugate acid is strong?**

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. HCl can only be a good proton donor, however, if the Cl- ion is a poor proton acceptor. Thus, the Cl- ion must be a weak base.

### Which conjugate acid is the strongest acid?

Thus the conjugate base of a strong acid is a very weak base, and the conjugate base of a very weak acid is a strong base. The conjugate base of a strong acid is a weak base and vice versa.

### Which acid has the weakest conjugate base?

As a result, we conclude that nitric acid has the weakest conjugate base.

**Is a weak conjugate base more stable?**

The key to understanding this trend is to consider the hypothetical conjugate base in each case: the more stable (weaker) the conjugate base, the stronger the acid. Look at where the negative charge ends up in each conjugate base.

## Is a stronger conjugate base more stable?

Therefore, if you want to determine the acidity of a compound, you can look at the stability of the conjugate base. The more stable the conjugate base, the more likely the acid is to donate a proton. Therefore, the more stable the conjugate base, the stronger the acid.

## Which is the weakest conjugate base?

Cl−

Cl− is formed from HCl which is the strongest acid and hence weakest conjugate base is Cl− Q.

**Which of the conjugate acid is the weakest acid?**

∴ HCl is the strongest acidic and Cl− is weakest conjugate base.

### Do weak acids have strong conjugate bases?

Weak acids have very strong conjugate bases while strong acids have weak conjugate bases.

### Which of the following acid has the biggest conjugate base?

The weakest acid is HClO. Therefore the strongest conjugate base is ClO– .

**Which conjugate base is most stable?**

It likes to have electrons around it and therefore it makes sense that fluorine is the best at stabilizing a negative charge and that makes this the most stable conjugate base.

## How do you know if a conjugate base is stable?

A conjugate base is more stable when the negative charge is on an electronegative element and when the charge is delocalized over multiple atoms. The more stable the conjugate base, the stronger the acid.

## How do you know which conjugate acid is the most stable?

**Which is the weakest conjugate acid?**

Cl− is formed from HCl which is the strongest acid and hence weakest conjugate base is Cl− Q.

### Which has the weakest conjugate acid?

### Which conjugate base is more stable?

And if this is the most stable conjugate base, the fluoride anion is the most stable conjugate base, that means that H-F must be the strongest acid.

**Which conjugate base is stronger CN or F?**

F – < CN – basic character.

## Which conjugate base is the strongest base?

CH3COOH is the weakest acid,hence it’s conjugate base is strongest.

## Which acids has the weakest conjugate base?

**How is the strength of an acid determined by its structure?**

The relative strength of an acid can be predicted based on its chemical structure. In general, an acid is stronger when the H–A bond is more polar. Acidity is also greater when the H–A bond is weaker and when the conjugate base, A⁻, is more stable.

### Which weak base has the strongest conjugate acid?

A weak base always ionizes into its conjugate acid or gives its strong conjugate acid and a strong base gives its weak conjugate acid. In base 2, Kb is very small hence, the base is very weak and gives its strongest conjugate acid. Therefore, the correct answer is base 2.

### Do weak bases have strong conjugate acids?

**Are Weaker bases more stable?**

## Is F or Cl A stronger base?

Not only is fluoride ion a stronger Bronsted-Lowry base than chloride ion (and heavier halides), so are hydroxide ion versus hydrosulfide ion and ammonia versus phosphine.
