4. The Debye-Huckel limiting law is strictly valid only in the limit of infinite dilution. A more widely applicable equation is the Debye-Huckel equation: 0.510 z,z_|V7 1+(0.328aT log Y This equation applies at 25 °C in dilute aqueous solution. For a 0.00100 m aqueous solution of CaCl2 at 25 °C, the y is found experimentally to equal 0.888. Use this to determine the value of the constant a (which is related to the ion size and has units of A)....
