Aluminum Chloride has a universal indicator color of red and the Ph of 4.0

Question

b) Sodium Carbonate has a universal indicator color of violet and the Ph of 9.5.
c) Ammonium Acetate has a universal indicator color of green and the Ph of 7.5

For the following salts give an explanation of these salts should have these Ph with an equation to show Hydrolysis????

Answer 1

Please read your post; perhaps you will see why no one is answering. You ask about "the following salts" but you don't list any salts.

Answer 2

Aluminum Chloride has a universal indicator color of red and the Ph of 4.0
b) Sodium Carbonate has a universal indicator color of violet and the Ph of 9.5.
c) Ammonium Acetate has a universal indicator color of green and the Ph of 7.5 ....For the following salts AlCl3, Na2CO3, C2H7NO2 give an explanation of these salts should have these Ph with an equation to show Hydrolysis????

Answer 3

See your post above. I wrote the hydrolysis equation which explains why Na2CO3 is basic in solution due to hydrolysis.
