Volume contraction occurs during the mixing of certain solvents
the verdict
SUPPORTED
the evidence backs this
confidence 85/100
Volume contraction frequently occurs when certain solvents are mixed, as evidenced by negative excess molar volumes driven by strong intermolecular interactions and efficient packing.
