Which one of the following method is commonly used method for destruction of colloid:
A
Dialysis
B
Condensation
C
Filtration by animal membrane
D
By adding electrolyte
Answer
By adding electrolyte
Explanation
Solution
When an electrolyte is added to a colloidal solution, it neutralizes the charge on the colloidal particles, causing them to come together and coagulate, forming larger particles that can settle or be easily removed from the solution. This process is known as coagulation and is commonly used to destabilize colloidal suspensions.
So, the correct option is (D): By adding electrolyte
