Which outcome occurs when the Debye-Hückel constant increases in an electrolytic solution?

A)Increased ion mobility in the solution
B)Decreased activity coefficients of ions
C)Reduced electrical conductivity of solution
D)Greater solvent dielectric constant value

💡 Explanation

When the Debye-Hückel constant increases, ionic strength rises, causing the ionic atmosphere around each ion to thicken because of greater charge density, leading to decreased activity coefficients via increased interionic interactions. Therefore, activity coefficients decrease, rather than increased mobility/conductivity or dielectric changes, which need different mechanistic conditions.
