An aqueous solution of KC2H3O2 will be basic. The K+ is the cation of a strong base (KOH), thus it is a neutral ion and has no effect on the pH of the solution. The C2H3O2- is from a weak acid (HC2H3O2), thus it is a basic ion.
So, is KBr a salt?
Potassium bromide, a typical ionic salt, is fully dissociated and near pH 7 in aqueous solution. It serves as a source of bromide ions. This reaction is important for the manufacture of silver bromide for photographic film: KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq)
Is Ki an acid or base?
The ions from KCl derive from a strong acid (HCl) and a strong base (KOH). Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt. Therefore the solution will be basic, and KNO 2 is a basic salt.
