Which substance form colloidal solution in water?a)glucose,b)urea,c)Baso4,d)starch
Answers
Colloidal solution is a solution in which the colloid mixes uniformly.
All colloids have a Tyndall Effect, which is not exhibited by glucose.
Starch is a colloid and thus when mixed with water can form the colloidal solution.
Thus, the correct option is (4) starch.
ANSWER:
Starch is a substance that can form colloidal solution in water.
EXPLANATION:
Colloidal solution is a mixture. In this mixture, the substances are suspended in a fluid.
The colloidal systems can occur in three states. They are,
- Solid
- Liquid
- Gas
But the colloidal solution is referred as a liquid concoction.
The particles of colloid can scatter a beam of light which passes through it and makes its path visible. This is known as Tyndall effect. Glucose does not show tyndall effect. The particles are not suspended in water. So, glucose does not form colloidal solution with water.
Urea is a true solution and there are no insoluble substances. So, urea does not form colloidal solution with water. Barium Nitrate does not exhibit tyndall effect. So, it does not form colloidal solution.
