  text: Electrostatic correlations between ions dissolved in water are known to impact
    their transport properties in numerous ways, from conductivity to ion selectivity.
    The effects of these correlations on the solvent itself remain, however, much
    less clear. In particular, the addition of salt has been consistently reported
    to affect the solution’s viscosity, but most modeling attempts fail to reproduce
    experimental data even at moderate salt concentrations. Here, we use an approach
    based on stochastic density functional theory, which accurately captures charge
    fluctuations and correlations. We derive a simple analytical expression for the
    viscosity correction in concentrated electrolytes, by directly linking it to the
    liquid’s structure factor. Our prediction compares quantitatively to experimental
    data at all temperatures and all salt concentrations up to the saturation limit.
    This universal link between the microscopic structure and viscosity allows us
    to shed light on the nanoscale dynamics of water and ions under highly concentrated
    and correlated conditions.
