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. WebThe pH of a buffer depends on the ratio [base]/[acid] rather than on the particular concentration of a specific solution. The exact ratio of the base to the acid for a desired pH can be determined from the K a value and the Henderson-Hasselbalch equation. For example: Suppose you wish to prepare a buffer solution to keep the pH at 4.30.
