Question

If a buffer solution is 0.270 M in a weak base (Kb = 4.7 x 10-5) and 0.480 M in its conjugate acid, what is the pH? - pH = L

Answer 1

Answer #1

Answer:-

This question is solved by using the simple concept of Henderson Hasselbach equation which involves the determination of pH.

The answer is given in the image,

Рише: - Let weak base = BOH So [BoH] = 0.270M [8+] = 00480M kr = 4.7x10-5 pkp = -logka E-log (4.7x10-5) = 4.33 pka=14-pkp. pk
