Thallous chloride, activity coefficient

Calculate the mean activity coefficient of thallous chloride, the solubility of which has been measured in water and in the presence of various concentrations of potassium chloride soiutions at 25 °C, as given in Tabie P.l. The soiubiiity of this salt in pure water is 1.607 x 10 mol kg". (Constantinescu)... 

The activity coefficients of thallous chloride at 25 , obtained in the manner described above, in the presence of a number of salts are given in Table XLI the data are recorded for solutions of various (total) ionic... 

TABLE XLI. ACTIVITY COEFFICIENTS OF THALLOUS CHLORIDE IN THE VARIOUS ELECTROLYTES AT 25 Added Electrolyte PRESENCE OP... 

The activity coefficients of thallous chloride, in the presence of various added electrolytes, determined from solubility measurements at 25 , are recorded in Table XXXII 1 m is the total molality of the thallous chloride and the added substance. It will be observed that in the more dilute solutions the activity coefficient at a given molality is independent of the nature of the other electrolyte present in the solution. The significance of this fact will be considered below. 

To calculate from solubility measurements values of the activity coefficient of thallous iodate in its saturated solution in the presence of potassiiun chloride and of potassium thiocj ate.
