Effects of neutral salts on solubility

The lyotropic or Hoffmeister series is a series of salts in which a gradation in properties including solubility is observed. This is illustrated in Table 9.3, in which the solubilities of gluten protein in 1.0 M solutions of sodium salts with different univalent anions are tabulated (Preston 1981). 

The reaction absorbs a large amount of heat from the surroundings, causing the temperature to fall below 0°C to freeze the water film and cement the board to the flask. The equation for the reaction is 

In demonstration 1, there must be a large increase in disorder to offset the increase in enthalpy in order for the reaction to proceed. What processes that cause the increase in disorder can be inferred from the equation for the reaction  

In demonstration 2, is it impossible to revert to the original ordered state of two separate layers by continuing to shake the tube  

Write brief notes to attempt explanations of the following observations
