Diprotic Acid

19
Q

A Brønsted-Lowry acid that can donate three acidic protons?

A

Triprotic Acid

20
Q

This is a proton acceptor and may be able to form a bond to a proton. It must also contain a lone pair of electrons that can be donated to form a new bond.

A

A Brønsted-Lowry base

21
Q

Examples of common bases include…

A 
NaOH- sodium hydroxide
Mg(OH)2- magnesium hydroxide
NH3- ammonia (with N having a lone pair) 
KOH- potassium hydroxide
Ca(OH)2- calcium hydroxide
H2O- water (with O having 2 lone pairs.
22
Q

What happens during the reaction of a Bronsted-Lowry Acid with a Brønsted-Lowry base?

A
  • The acid donates a proton to the base which accepts H.

- One bond is broken and one bond is formed.

23
Q

A

Conjugate base

24
Q

The product formed by gain of a proton by a base in a Bronsted-Lowry reaction?

A

Conjugate Acid
