With regard to gelatin , which is true ? Question 8AnswerIt is lyophilic with water It is lyophilic with alcohol It is associated sol with alcohol It is lyophobic with water A gel is formed using cold water
Solution
The correct answer is "It is lyophilic with water".
Here's why:
Gelatin is a substance derived from collagen, a natural protein present in the tendons, ligaments, and tissues of mammals. It is used in food, pharmaceuticals, photography, and cosmetic manufacturing.
Lyophilic means 'liquid-loving' and in the context of colloids, it refers to particles that are attracted to the liquid in which they are dispersed. Gelatin, when mixed with water, forms a colloidal solution because the gelatin particles are dispersed throughout the water and they do not settle out. This is because gelatin is lyophilic with water, meaning it has an affinity for water.
On the other hand, gelatin is not lyophilic with alcohol. When mixed with alcohol, gelatin does not form a solution but rather precipitates out of the solution.
