Please answer the 4th question.

Dear Student, 4. Such questions are given to test the thinking ability of students and need to be answered by the student. However, I am providing you with the main concept of this activity. Chalk is insoluble in water and forms a heterogeneous mixture when mixed with water. As chalk is heavier, therefore it will settle at the bottom of the mixture when it is left undisturbed for sometime. Thus, water can be separated from chalk powder by sedimentation, decantation and filtration. You can frame your answer and get it checked by the experts by posting it on ask and answer portal. Regards
