Na2SO4, composition

In most cases, the maximum concentration represents the composition of the saturated solid at 25 °C. For example, the concentration of NaCl(cr) at 25 °C is 6.11m (Fig. 3.4). An example where this is not the case is Na2SC>4, where the maximum concent at ion of 4.0 m is twice the concentration at equilibria with Na2SO4 10H2O(cr) at 25 °C. In this particular case, we extended... [Pg.29]

The molten sodium sulphate/sodium silicate system of composition Na2SO4 Na2O-SiO2 has one liquid phase at 1475 K, but as the proportion of silica increases, the melt separates into two layers (, 2). The change from the miscible to immiscible phase of the system has been explained by alterations in the silicate structure as the ratio of Na20 to Si02 decreases. In more basic, less viscous melts, the silicate ions exist in the form of SiO "... [Pg.306]
