Description

A study was made of the effect of P, N, T and pH on the solubilities of chlorine in concentrated sodium chloride solution.<BR>The experimental range of P was from 0.1 to 1.0atm, N from 210 to 300g/L, T from 303 to 343°K (from 30 to 70°C), pH from 1 to 5. The results obtained of the solubilities which might be cosidered the sum of [Cl2(aq)], [Cl3-] and [HClO] were as follows:<BR>The effect of pH on [HClO] is given by Eq. (5). In the range of pH less than 3, where [HClO] is found to be approximately negligible, the relation between solubilities and P is explained by Henry's law, [Eq. (10), ] and the effect of N by Eq. (11). Hence, calculation of the solubilities of unhydrolyzed chlorine in th pH range given above are made by means of the following empirical equation:<BR>where P=0-1.0, N=200-300, and T=303-343.<BR>This value can also be obtained graphically by employing the nomograph of Fig. 10 which is prepared from the above equation.
