The following set of solutions are prepared by dissolving the requisite amount of solute in water to obtain the desired concentrations. The pressure of the system is then manipulated such that movement is from the solution listed first to the solution listed second. Classify each set of solutions based on the movement of solvent from the first solution listed to the second solution listed as osmosis or reverse osmosis.
a. 2.1 M HNO3 to 1.2M HNO3
b. 0.05M sucrose to 5M sucrose
