Answer & explanation
Correct answer: option 2
|
Lyophilic colloid |
Lyophobic colloid |
| a) The lyophilic solvent is usually water loving. | a) The lyophobic solvent is usually water-hating species. |
| b) They have a greater affinity for the medium's dispersion, and when the water medium disperses them, they are generally named hydrophilic. |
b) The have less affinity for the medium's dispersion, and when the water medium disperses them, they are generally named as hydrophobic. |
| c) The lyophilic solvent gives a reversible reaction. |
c) The lyophobic solvent gives an irreversible reaction. |
| d) The lyophilic sol has weak Tyndall effects. | d) The lyophobic sol has strong Tyndall effects. |
| e) The lyophilic particles are generally not detectable under an ultra microscope.Examples of lyophilic colloids are starch or protein dissolved in water. |
e) The lyophobic particles are generally detectable under an ultra microscope.Examples of lyophobic colloids are aluminium hydroxide and ferric hydroxide dissolved in water. |
