    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?

    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.

    why don't you use sodium acetate with rollin boiled water like the experiment asked?

    Rollin boiled water?

    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.

    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.

    Is that what's going on here? Is this thread really about cooking up crack?

    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.
