Q

Define weak acids

A

Weak electrolytes and don’t ionize 100% in aqueous solution. Ka has a number

17
Q

How to determine if it’s a strong Acid

A

If it’s very large it is a strong acid and breaks down completely (disassociation equation). Balanced equation and then ratios.

18
Q

How to determine if it’s a weak acid

A

We will be given the Ka and it will not completely disassociate. Use Ka formula and then square root

19
Q

How to determine which part is the base

A

Will have OH, group 1 and 2 of the periodic table will be strong
