Electrostatic solvation energy ΔG_cg (in kJ∕mol) of a sodium ion in water obtained in this work in simulation boxes of different sizes L. Finite-size corrections ΔG_c are evaluated separately from the charging free energy $\Delta G_{\mathrm{cg}}^s$ computed directly in the simulations (explained in the text).

L ( Å)	$\Delta G_{\mathrm{cg}}^s$	ΔGc	ΔGcg

45	−457	−33	−490
60	−465	−20	−485
