Sodium acetate is a sodium salt of acetic acid, very widespread substance. It is widely applied both in the industry, and in life. It is used in production of various dyes, and it is also applied to tanning of skin. In medicine is diuretic, in the food industry it is used as preservative, etc.
It is required to you
- Acetic acid, baking soda, laundry soap, water, test tubes, glass capacity.
Instruction
1. Take glass capacity and fill in it a little ordinary baking soda (sodium a hydrocarbonate). Then, fill in baking soda with acetic essence. Impassioned reaction with formation of acetate of sodium, carbon dioxide and water will begin.
2. Mix solution until reaction does not stop. Further, take two small test tubes and fill them with solution. To one test tube add acetic acid, and to other baking soda, it will be test on surplus or a lack of any reagent. For example, if at addition of acetic acid carbon dioxide is emitted, it means that in solution there was not reacted soda and it is necessary to add acid for its clearing to the general capacity.
3. Repeat similar actions before full neutralization of solution. That is until solution does not cease to react to addition of soda or acid.
4. Then, put the container with solution on heating. Liquid will be evaporated, and at the bottom of a vessel there will be a sodium acetate.
5. Pour water in a metal cup and put it to heat up. Further, when water will heat up (not to boiling), dissolve in it a little laundry soap.
6. After that, add acetic acid to solution. As a result of reaction to the surface of liquid, white substance will emerge - it is mix of stearin and palmitic acids, and solution will contain sodium acetate.
