Look at sample problem 18.15 in the 8th ed Silberberg book. Identify the Lewis acids and Lewis bases in the following reactions: H+ + OH- <-> H2O Lewis acid: Lewis base: Cl- + BCl3 <-> BCl4- Lewis acid: Lewis base: K+ + 6H2O <-> K(H2O)6+ Lewis acid: Lewis base:

Respuesta :

Answer:

1. H+ + OH- <--------> H2O

H+ is a Lewis acid

OH- is a Lewis base

2. Cl- + BCl3 <---------> BCl4-

Cl- is a Lewis base

BCl3 is a Lewis acid

3. K+ + 6H2O <------> K(H2O)6+

K+ is a Lewis acid

H2O is a Lewis base

Explanation:

By definition, Lewis acid is an electron pair acceptor while a Lewis base is an electron pair donor.

Potassium ion accept electron pairs from 6 water molecules which donate the electron pairs.
