In an amino acid, the carboxyl group ionises at p K_ a₁ =2.34 and ammonium ion at p K_ a₂ =9.60 . The isoelectric point of the amino acid is at pH

Options

  1. A4.32
  2. B3.34
  3. C9.46
  4. D5.97

Correct answer

D. 5.97

Step-by-step solution

Isoelectric point, pH = p K_ a 1 + p K_ 2 = 2.34+9.60 2 =5.97
