Vedclass · Answer

(A) Blood is a negatively charged colloid due to the presence of negatively charged ions on the surface of blood cells. Therefore,the statement that blood is a positively charged sol is incorrect.Soap solution contains ionic micelles as colloidal particles,which form above the $CMC$ (Critical Micelle Concentration).Blood is purified by the process of dialysis,which removes waste and unwanted particles from the blood.Chemical adsorption (chemisorption) typically increases initially with temperature due to the activation energy required for bond formation,but it decreases at higher temperatures as the exothermic process becomes less favorable.
