A sample of red ink (a colloidal suspension) is prepared by mixing eosine dye, egg white, HCHO and water. The component which ensures stability of the ink sample is :

Options

  1. AEgg white
  2. BWater
  3. CHCHO
  4. DEosin dye

Correct answer

A. Egg white

Step-by-step solution

Blue ink is a colloidal sol, so it can be stabilised by material like natural gum or Egg white/albumen.
