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????

    Na2CO3. The CO3^-2 ion hydrolyzes as follows:
    CO3^-2 + HOH ==> HCO3^- + OH^-
    Thus you see OH^- is produced; the pH should be basic. By the way, it is pH and not Ph.
