sodium acetate supersaturated solution
« on: September 30, 2023, 02:25:49 AM »
hi guys
I want to do the instant freezing experiment with sodium acetate super saturated solution. I need sodium acetate 3.H2O for this reason but instead I have anhydrous of this salt. I wanted to ask do I have to add more water to see the results, and if so, how much more?
(for sodium acetate 3.H2O I have to add 160 gr sodium acetate 3.H2O with 30 gr of water to achieve supersaturated solution)
thanks for your help in advance

Yes, you need more water and less solid when starting from the anhydrous salt. This can be easily calculated - first step will be to find out (using molar masses of sodium acetate and water) how much water is present in the 160g of CH3COONa·3H2O.
