5.The ionic product of an aqueous solution (a solution with water as the solvent),
symbolized Kw, is defined by the equation Kw= [H*(aq)] * [OH-] where the brackets
denote the concentrations (in moldm-) of H*(aq) and OH ions at that temperature. What
are the units of Kw? Calculate Kw for a solution at 25 °C if [H(aq)] = 5 x 10-1° moldmº
and [OH-] = 2.0 x 10- moldm. Express your answer to the correct number of significant
figures.
