Solution: Identify the following salts as neutral acidic or basic:i) LiNO3ii) SrBr2iii) LiF iv) KCN v) NH4ClO4vi) NH4Brvii) NH4CNPlease include why are they neutral basic or acidic.

Problem

Identify the following salts as neutral acidic or basic:

i) LiNO3

ii) SrBr2

iii) LiF 

iv) KCN 

v) NH4ClO4

vi) NH4Br

vii) NH4CN

Please include why are they neutral basic or acidic.

Solution

Some rules for identifying salts:

Positive Cations:

1. Transition metals need to have +2 or higher charge to be acidic, if less than +2 they are neutral.

2. Main-group metals need +3 or higher charge to be acidic, if less, they are neutral.

3. Positive amines are acidic.

Anions:
