you put it in the freezer
http://www.instructables.com/id/Sodium-Acetate/ (but the soduim acetate will not be pure enough to make hot ice, ive tried it) go here for a good guide on how to make it
yes
Acetic acid
Yes, you can make sodium acetate from baking soda. First, create a solution of baking soda and vinegar. Then heat the solution to drive off carbon dioxide and leave behind sodium acetate. Allow the solution to cool and crystallize to obtain solid sodium acetate.
you have to be really smart to do that
To make sodium acetate at home, mix vinegar (acetic acid) with baking soda (sodium bicarbonate) in a container. Heat the mixture until it evaporates and forms crystals. Filter the crystals to separate them from the liquid. This process creates sodium acetate, which can be used for various purposes.
you use vinegar and baking soda
Yes. You can boil a mixture of sodium acetate in water and subsequently cool it. If you cause it to precipitate, it will feel hot.
Sodium acetate buffer is a commonly used buffer solution in biochemical and molecular biology laboratories. It consists of a mixture of sodium acetate and acetic acid, and helps maintain a stable pH when added to solutions. It is effective in the pH range of around 4.7 to 5.7.
To prepare a 0.38 M sodium acetate solution, you would need to dissolve the appropriate amount of sodium acetate trihydrate (CH₃COONa·3H₂O) in water. For example, to make 100 mL of a 0.38 M solution, you would dissolve 2.96 grams of sodium acetate trihydrate in sufficient water to make 100 mL. Ensure complete dissolution before use.
To prepare 0.1 M sodium acetate, you will need to weigh out the appropriate amount of sodium acetate trihydrate or anhydrous sodium acetate based on the molarity you desire. Dissolve this in a specific volume of water, typically in a volumetric flask, and then make up the final volume to the desired concentration. Stir well to ensure complete dissolution.
