Webexpressed in the terms of percent saturation • It is the concentration of salt in a solution as a percent of the maximum concentration possible at a given temperature. V (ml) = 100 (S 2-S 1) 1 –S 2 – V is the volume of the saturated salt needed. – S1 is the initial low saturation ( used as a decimal). – S2 is the final high saturation ... WebAdd a seed crystal of sodium acetate to the flask. The supersaturated solution will crystalize and give off heat. Discussion When solid sodium acetate trihydrate is heated above 58ºC it loses its water of hydration and begins to dissolve in that water. The salt becomes completely dissolved at 79ºC.

WebScratch the bottom of the flask gently with a stirring rod. Add a bit of solid as a seed crystal. If crystal growth does not start on its own after the solution in the flask returns to room temperature, identify the best ways to promote this process. Select one or more: Place the flask on a hot plate to evaporate some solvent. WebBefore all the water has evaporated, you should find some crystals forming on the bottom of the beaker. Filter the solution. Collect the crystals from the filter paper onto a paper towel. Teaching notes Practical points. The safety warnings in stage 1 of the procedure are particularly relevant to younger or more inexperienced students.
