1. If the Ka of CH3COOH is 1.8 x 10^ -5, what is the Kb of CH3COONa?


2. Give the lewis acid and base in the left side of the equation: FeBr3 (s) + Br- = FeBr4-

3. Give the acid-base neutralization reaction that produces the salt NH4Cl.

I would appreciate help,

Thanks.

1) Kb= Kw/Ka >>> Kb=(1E-14/1.8E-5) = 5.5E-10

2) FeBr3 is the lewis acid and Br- is the lewis base

3) NH3 + HCl >>> NH4CL

I beleive you have only a very fundamental understanding of the subject matter and need to review the chapter. This is fundamental and you need to understand it.

The Kb = Kw/Ka - this can be seen from fundamantal algebra on the mass action expressions.

Lewis acid is an electron pair accepter; Br- has the electrons to donate

HCl + NH3 =. NH4Cl

Again master the material as you cannot pass the test with your level of understanding
