Q25. incorrect statement is : (c.) A Lewis base acts as an electron pair acceptor.
ascorbic acid pH of buffer : 3.96
Explanation
Ka = 6.8 x 10-5
pKa = -log(Ka)
pKa = -log(6.8 x 10-5)
pKa = 4.17
pH = pKa + log([conjugate base] / [weak acid])
pH = pKa + log([NaHC6H6O6] / [H2C6H6O6])
pH = 4.17 + log(0.50 M / 0.80 M)
pH = 3.96
