I found the following detailed description (for another salt) for such an experiment for you: "The Effect of Temperature on Solubility" at ( http://129.93.84.115/Chemistry/DoChem/DoChem065.html#Description ) The idea is to solve weighed samples of the salt in water, heat the solution and then watch for the appearance of solid in the solution: "Description Students are given weighed samples of a soluble salt such as potassium nitrate. The sample is added to 20 mL of water and heated until all of the salt dissolves. The solution is cooled, and the temperature at which solid appears is noted. A solubility curve is prepared by pooling the data from all of the students." (see above) All you got to do is find out reasonable amounts of Na2SO4 for the amount of solvent by making a supersaturated solution. I hope this help you to solve the problem. till-ga |

A chemical with that formula does not exist. Did you mean Na2SO4 ? till-ga |
