Web5 de nov. de 2024 · We can also compare the surface charge densities on the two spheres: E1 = σ1 ϵ0 E2 = σ2 ϵ0 ∴ σ2 σ1 = E2 E1 = R1 R2 ∴ σ2 = σ1R1 R2 and we find that the charge density is higher on the smaller sphere. Thus, there are more charges per unit area on the smaller sphere than the bigger sphere. Web9 de jul. de 2024 · The charge density is more for smaller ions and hence the smaller ions have higher values of hydration enthalpy. The higher the charge density the higher will be the force of attraction between the ion and the water polar end. This makes the value of hydration enthalpy higher in smaller ions.
