Question

Define strong and weak bases . List four names of each . Write two uses of each.​

Answer 1

Answer:

Strong base: A base which completely ionises in water and produces a large amount of hydroxide ions. Weak base: A base which is partially ionised in water and produces a small amount of hydroxide ions and please subscribe to this channel gamerz beast

Answer 2

Answer:

Strong Bases:

A strong base is something like sodium and potassium hydroxide that is fully ionic.

It dissociate almost completely in an aqueous solution.

Example of strong bases.

1. Sodium Hydroxide (NaOH).
2. Potassium Hydroxide (KOH).
3. Calcium Hydroxide (CaOH2).
4. Ammonium Hydroxide (NH4OH).
5. Caesium hydroxide (CsOH)

Uses of strong bases:

1. Strong bases ionizes' almost completely in aqueous solutions.
2. As well as, it conduct electricity very well since they are electrolytes.
3. It have a Ka value of greater than 1.
4. Lastly, strong bases have a pKa value that is negative.

Weak Bases:

Weak base is a chemical base that does not ionize fully in an aqueous solution.

Weak bases dissociate to only a small extent or dissociate partially in solution.

Examples of weak bases:

1. Ammonia (NH3).
2. Diethyl amine (CH3CH2)2NH.
3. Methylamine (CH3NH2).
4. Sodium bicarbonate (NaHCO3).

Uses of weak bases:

1. Weak bases do not ionizes' completely in an aqueous solutions.
2. As well as, it conduct electricity poorly since they are weak electrolytes.
3. Weak bases have a Ka value of less than 1.
4. It have pKa value that is positive.
