The K a for acetic acid is 1.7 x 10-5. Buffer Solution. Buffers are broadly divided into two types – acidic and alkaline buffer solutions. 0000002951 00000 n 2- Realize the way by which the buffer stabilizes the pH . The aqueous solution of a salt of a strong acid and a strong base is neutral, as neither the anion nor cation undergoes hydrolysis. वाणिज्यिक बैंक वे संस्थाएँ है जो....... का व्यवसाय करती हैं।है, haa to pir hui na aunty... hehe XD XD .....
