Effective ph range of buffer
WebThe ammonia buffer would be effective between pH = 8.24 - 10.24. The acetate buffer would be effective of the pH range from about 3.74 to 5.74. Outside of these ranges, … WebBuffers resist changes in pH when small amounts of acid or base are added. The effective pH range of a buffer depends on the pk, of the acid and the relative concentrations of the acid, HA, and its conjugate base, A A buffer is effective when the ratio of the acid:base concentrations is between 10:1 and 1:10.
