A semipermeable membrane separates two solutions. On one side of the membrane the concentration of sodium ions is 0.87 mol/L, and on the other side the concentration of sodium ions is 2.5 mol/L. Which statement is true? Please conduct an internet search on "osmosis" to help you answer this question.
Sodium ions will flow from the 2.5 mol/L solution through the membrane into the 0.87 mol/L solution.
Sodium ions will flow from the 0.87 mol/L solution through the membrane into the 2.5 mol/L solution.
Water will flow from the 2.5 mol/L solution through the membrane into the 0.87 mol/L solution.
Water will flow from the 0.87 mol/L solution through the membrane into the 2.5 mol/L solution.
