Dialysis and Its Applications in Colloid Separation starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Dialysis and Its Applications in Colloid Separation.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A colloidal solution contains both NaCl and glucose as impurities. Which process would you use to remove both?
A colloidal solution is placed in a bag made of cellophane and immersed in distilled water. After some time, the conductivity of the water increases. What does this indicate?
A protein solution is contaminated with sodium chloride. Which method would you use to remove the salt without losing the protein?

Describe one limitation of dialysis in colloid separation.
Describe the effect of increasing temperature on the rate of dialysis.
Describe the main difference between dialysis and ultrafiltration in colloid separation.
Explain the principle behind the separation of ions from colloidal particles during dialysis.
Explain why colloidal particles do not pass through the dialysis membrane.
Explain why dialysis is important in the preparation of pure colloidal solutions.
Explain why dialysis is not suitable for separating colloidal particles of similar size.
Explain why frequent replacement of the external water during dialysis is necessary.
