Consider a saturated solution of MCl3 with a molar solubility of 0.18 M. What do you expect to see when you add 0.1 M NaCl to the solution (assume that there is no change in volume) The reaction will shift left The reaction will shift right The reaction will not be affected As a result of which The molar solubility will increase The molar solubility will decrease The molar solubility will remain unchanged
