Determining if a salt is Acidic or Basic

[Kayley Steele 3D]

How do we determine if a salt is acidic, basic or neutral. I know first you determine if each cation is derived from a strong or weak base but then i'm unsure of what's next.

Hi!

A salt is basic if when you look at the anion, it is the conjugate base of a weak acid. A salt is acidic if when you look at the cation, it's the conjugate acid of a weak base. Hope this helps!

A salt is going to dissociate in water. If the cation is the conjugate acid of a weak base, that means it will react with water and produce H+ ions. This makes the solution acidic. If you look at the anion and see that it is a conjugate base to a weak acid, then after it dissociates from the salt, it will react with the water to gain an H+ ion and produce OH- ions, making the solution basic. If the ion from the salt reacts forms a strong base or acid, then it will stay dissociated and not change the pH. Hope this helps!

If the anion of a salt is derived from a weak acid, it makes the solution basic. Therefore, a basic salt contains an anion that is the conjugate base of a weak acid and a cation from a strong base.
If the cation in a salt is derived from a strong base it does not affect the pH. If the anion in a salt is derived from a strong acid it does not affect the pH. Therefore, a neutral slat is one that contains a cation from a strong base and an anion from a strong acid.

If the cation is from group 1 or two then only include the anion, this means the salt is basic because the h+ from water will dissociate and leave OH- in solution.
If the anion is that of a strong acid then only include the cation, this means the salt is acidic because the H+ will go to water and leave H30+ in solution.

If the cation is the conjugate acid of a weak base, then it is an acidic solution

If the cation is a small highly charged metal cation (like Al3+ or Fe3+), then it is an acidic solution.

If the anion is the conjugate base of a weak acid, then it is a basic solution.

It is neutral if:
the anion is the conjugate base of a strong acid and also the cation is the conjugate acid of a strong base.
