WebCH3COOH pKa=4.76 c=0.1. HCl pKa=-10 c=0.1. Case 2. Solution is formed by mixing known volumes of solutions with known concentrations. For each compound enter compound … WebMar 13, 2024 · 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. Is kch3co2 acid or base? Potassium acetate (KCH 3CO 2) is the potassium salt of acetic acid.
