Agroup of students is in the laboratory performing an experiment on the effect of adding salt to water. which observation are students likely to make as they increase the molality of the saltwater solution? as the molality increases by 1 m, there is a corresponding decrease of 1.86°c in the solution’s freezing point. as the molality increases by 1 m, there is a corresponding increase of 1.86°c in the solution’s freezing point. as the molality increases by 1 m, there is no observable change in the solution’s freezing point. as the molality increases by 1 m, there is an initial decrease of 1.86°c followed by an increase of 1.86°c in the solution’s freezing point.
