Predict wheter a solution of each of the following salts is acidic, basic, or neutral.?

Question

For salts that form acidic or basic solutions , write a balanced equation for the reaction.
1. NH4BR
2. KNO2
3.Mg(NO3)2
4. BaF2
5.K2S

Answer 1

Metal salts form basic solutions
Non-metals form acidic solutions.

Look up the exceptions on google.

Answer 2

1 is acidic
2 and 5 are alkaline

For an acidic one, make the cation lose a proton:
(NH4)+ -----> NH3 + H+

For an alkaline one, make the anion react with water, gaining a proton and forming OH-. I'll do one for you:

(NO2)- + H2O ----> HNO2 + OH-

Answer 3

Check out your acid / base tables.
