Question

CuSO4 Crystal The saturated CuSO4 aq shown above is left uncovered on a lab bench at a constant temperature As the solution evaporates 1 0 mL samples of the solution are removed every three days and the SO 2 in the samples is measured It is observed that the SO in the solution did not Change over time Which of the following best helps to explain the observation As the solution evaporates Cu aq and SO 2 aq leave the beaker along with the water molecules A B D As the solution evaporates the dissolution of CuSO4 s in the beaker decreases The evaporation of water is endothermic so more CuSO s dissolves exothermically in the solution which increases the SO Saturated CuSO4 aq As water evaporates more CuSO s precipitates out of the solution in the beaker
