Question
A) Classify each of the following salts as acidic, basic, or neutral.
Hint, you might need to look up Ka and Kb values in tables in your text (Chapter 16 or Appendix D) or lecture notes. You also might need to solve for Kb if Ka is given and vise versa.
CuBr3
Li2SO4
NaNO2
(CH3NH3)Cl
neutral
acidic
basic

- A. B. C.CuBr3
- A. B. C.Li2SO4
- A. B. C.NaNO2
- A. B. C.(CH3NH3)Cl
A.neutral
B.acidic
C.basic
Explanation / Answer
CuBr3 --> forms Cu + H2O = Cu(OH)2 + H+; slighly ACIDIC
Li2SO4 --> strong acid/base, NEUTRAL
NaNO2 --> NO-2 + H"O = HNO2 + OH- ; BASIC
(CH3NH3)Cl --> (CH3NH3+ + H2O = (CH3NH2 + H3O; ACIDIC
Na2CO3 --> BASIC
NaCl -- strong/Acidbase so NEUTRAL
ZnCl2 --> Slightly ACIDIC
KNO2 --> slighlty basic since it is a salt from a weak acid
