Acidity or Basicity of Salt Solutions.

Will 0.10 M aqueous solutions of the following salts be acidic , basic or neutral?
(Assume a solution is neutral if its pH is 7.00±0.05).

ammonium sulfite ((NH4)2SO3)

sodium citrate (Na3C6H5O7)

sodium hydrogen ascorbate (NaHC6H6O6)

ammonium formate (NH4CHO2)

I couldn't possible do better than this site. Read carefully and you can't go wrong. https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_Chemistry_Textbook_Maps/Supplemental_Modules_(Physical_and_Theoretical_Chemistry)/Acids_and_Bases/Acids_and_Bases_in_Aqueous_Solutions/Aqueous_Solutions_Of_Salts
In addition you can write equations for each of these and actually calculate the pH or pOH the same way I worked the C2H5NH3Cl problem.
Post your work if you get stuck and please be specific about what trouble you have and what exactly you don't understand.
