When 25 ml of and 25 ml of toluene is mixed, the total volume of the solution will be — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Mixing of carbon tetrachloride ($CCl_4$) and toluene (C7H8) shows a positive deviation from Raoult's law. This is because the intermolecular forces in the mixture are weaker than those in the pure components, causing the molecules to move slightly further apart. Thus, ΔV_mix > 0, and the total volume is greater than 50 ml.
