In the Lewis acid-base reaction…?

In the Lewis acid-base reaction:

Answer 1

Co{3+} + 6NH3 –> Co(NH3)6 {3+}

Acid is the species donating a positive charge
Base is species accepting the positive charge
adduct is the species formed (1 molecule formed from 2 or more other molecules)

Ammonia donates a lone pair of electrons to form a bond with the positively charged Cobalt forming a Cobalt-ammonium addcut.

Ammonia = Lewis Base
Cobalt = Lewis acid
