Q24 / 125 · BITSAT 2014 · Chemistry

The isoelectric-point of a colloidially dispersed material is the $\mathrm{pH}$ value at which

  • A
    the dispersed phase migrate in an electric field.
  • Correct answer
    B
    the dispersed phase does not migrate in an electric field.
  • C
    the dispersed phase has $\mathrm{pH}$ equal to 7 .
  • D
    the dispersed phase has pH equal to zero.

Solution

At isoelectric point there is no migration of dispersed phase in an electric field.

Hence, the correct answer is option: 'B'.
