In some solutions, the concentration of H 3 O + remains constant even when small amounts of strong acid or strong base are added to them. These solutions are known as :

Options

  1. AIdeal solutions
  2. BColloidal solutions
  3. CTrue solutions
  4. DBuffer solutions

Correct answer

D. Buffer solutions

Step-by-step solution

In acidic Buffer solutions when pH = pKa + log Salt Acid pH is not disturbed i.e H 3 O + , remains constant on addition of small quantity of acid or Base.
