Abstract The dielectric properties of water of various degrees of purity are measured at room temperature between 20 Hz and 1 MHz. Dielectric properties of deionized water containing different concentrations of copper sulphate are also presented. The results are in fair agreement with Coelho's theory of the space charge response of a medium containing mobile ions only when an additional contribution to the permittivity arising from DC conduction in the electrolyte is taken into account. This condition is consistent with the assumption that the carriers are free electrons of high mobility and low number density. It is noted that this is a very surprising result.
