Question

Classify these salts as acidic, basic, or neutral. K2SO3,NA2S,KCL,LIBR,NH4BR

Answer 1

1) NH4Br - I know enough to say that this is a salt of a weak base (NH3) and a strong acid (HBr). The NH4+ reacts like this in solution: NH4+ + H2O <==> H3O+ + NH3
That solution is acidic.

2) Na2S - basic for sure.


3) KCl - not 100% sure if it is dead on, but pure KCl solution has a pH of about 7; thus, neutral.

4)K2SO3-base as it is a salt of a strong base and weak acid.

5)LIBR is Neutraal
