Use the following table to answer the question. strong acids weak acids weak bases strong bases hbr ch3cooh nh3 naoh hno3 hf nh4oh koh h2so4 hcn ca(oh)2 which of these is a neutral salt? na2so4 nacn kf (nh4)2so4

The correct answer is

Explanation:

We are given some acids and bases and they are further classified into weak and strong acids & bases.

A neutral salt is formed wither from the combination of weak acid and base or by the combination of strong acid and base.

From the given options:

Option 1:

This salt is formed from and NaOH which is a strong acid and strong base. Thus, this salt is considered as a neutral salt.

Option 2: NaCN

This salt is formed from HCN and NaOH which is a weak acid ans strong base. Thus, this salt is considered as a basic salt.

Option 3: KF

This salt is formed from HF and KOH which is a weak acid ans strong base. Thus, this salt is considered as a basic salt.

Option 4:

This salt is formed from and which is a strong acid and weak base. Thus, this salt is considered as an acidic salt.

From the above information, we conclude that the correct answer is salt.

it's 3.2 on edge, i just took the test.
