Hi, Its been a while since I was last here... Why I am back here is because I hope we still have someone here who can explain something form me. I tried to make sodium ethanoate by mixing backing soda and vinegar. About 80 g of first and 100 ml of 5 % vinegar. The experiment was looking OK, until I started to vaporize the water from it. Then the solution turned really viscose and sticky like glue. I would imagine that the baking soda was not pure sodium bicarbonate.
I don't think you're using enough vinegar, and it could do with being more concentrated. What do you plan to do with the sodium ethanoate anyway?
http://en.wikipedia.org/wiki/Sodium_acetate Naat, I think you got what you were looking for. Sodium acetate is like that.
Actually I wanted do try that "hot ice" experiment. As an extra, I am thinking about participating in a The Grand Prix Chimique I thought that lack vinegar may be to blame, but adding it didn’t cause the solution to form bubbles, thus I presumed the reaction was over.
Rollin boiled water? Please Register or Log in to view the hidden image! I thought they advised to get it from internet. I had vinegar and baking soda in my kitchen.
I don't think sodium acetate is the same as baking soda. Chemistry can be unpredictable, its always good to follow exact directions.
Of course it is not. Why would I mess with vinegar? But when you combine baking soda and vinegar, you should get sodium acetate (a.k.a. sodium ethanoate) CH3–COOH + Na+[HCO3]– → CH3–COO– Na+ + H2O + CO2 Baking soda should contain a large % of Sodium bicarbonate. ... I didn`t find (or looked for) any directions. NB! I did use regular tap water, could that be it?
Your problem is probaby impurities from commercial Vinegar and baking soda. Plus there might be other processes involved in making a sodium acetate from your conponents.
I think the agreement is that your vinegar is not concentrated enough, and/or your baking soda is commercial, and may have impurities. Try getting them from a chemical supplier.
I bake a lot and baking soda doesn't last forever. Did you use a new box or one that has been freshening up the fridge for a year?
thats a difficult question, if you look at it from a philosophical point of view then maybe it could be. peace.
you should always use fresh bicarbs when cooking up crack, . you can wash coke with ammonia to make freebase. its the first science lesson you should ever learn. peace.
