Which outcome occurs when the van't Hoff factor deviates significantly from ideal values in a solution?

💡 Explanation

When the van't Hoff factor deviates, ion pairing or solvation occurs, altering the effective number of particles in solution because solute-solute or solute-solvent interactions do not behave ideally, leading to inaccurate osmotic pressure readings. Therefore measurement error increases, rather than lower solubility, slower equilibrium, or better boiling point accuracy because these relate to other non-idealities.
