View Full Version : Baking soda + vinegar
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.

nietzschefan 06-10-07, 01:11 PM that is not nice
phonetic 06-10-07, 04:14 PM 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?
tablariddim 06-10-07, 05:00 PM I used to do that in my growing room...or was it soda?

Naat, I think you got what you were looking for. Sodium acetate is like that.
Actually I wanted do try that "hot ice" experiment (http://www.youtube.com/watch?v=jwRro4mXfKs).
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.
why don't you use sodium acetate with rollin boiled water like the experiment asked?

Rollin boiled water? :confused:
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?

you should use pure bicarbs if your cooking up crack.
peace.

Just look it up on Wikipedia. You already got sodium acetate. It's supposed to be like that.
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.
Positron 06-17-07, 06:37 PM 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.
let us know how its turns out please, the experiment looks pretty cool

Is that what's going on here? Is this thread really about cooking up crack?
Orleander 07-10-07, 07:18 PM 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.

CRAP!! I thought it was how to make kool-aid. :grumble:
jerk

sorry i dont know how to make koolaid. im sure its not a scientific as making crack though.
peace.

Thanks EFC! that's good to know...you never know when Flava-flav might stop by with his posse. Wouldn't want to look like a newbie...wouldn't that be an embarrassing hosting feux pas.

or if your broke and need alot of cash fast, or want 2 conduct a science experiment for class.
