Which of the following mixtures have components which can be separated by filtration A. Colloids B.solution C. Suspension D. All of the above Which of the following mixtures have components which can be separated by filtration A. Colloids B.solution C. Suspension D. All of the above A. Colloids B.solution C. Suspension D. All of the above Solution answer = option C = Suspension. Suspension is heterogenous mixture contain solid particles present in solution which are visible to naked eye. so we can separate by simple filtration. colloids and solutions we cannot separate by filteration answer = option C = Suspension .
