Concept explainers
To calculate: Whether option (1) placing the dialysis bag in 4L of distilled water for 12h or option (2) placing the dialysis bag in 1L of distilled water for 6h and then in another 1L of fresh distilled water for another 6h is more effective to remove much NaCl from the given sample.
Concept introduction: Water is the most abundant, colorless, odorless, and tasteless character that explains the fundamental importance to living organisms. Molecules generally diffuse across a permeable membrane from a region of higher concentration to the region of lower concentration. During dialysis, solutes diffuse across semi-permeable membrane from the region of higher concentration to the region of lower concentration.
