    Heating in a test tube a small amount of sodium nitrate and sodium acetate (hot ice) it will melt, bubble when molten hot, then when it stops bubbling it explodes. I found this out just messing around and didn't understand why. That why I looked for a video, any idea?

      the acetat ion is made of carbon, hydrogen and oxygen. if you have a good oxidizer like a nitrat it will react. it will also react with ascorbates. the sodium reacts to its oxide or its carbonate

      @@h.a.4286 Yes but it's unusual that it spontaneously explodes unconfined. Even a mixture with Magnesium or other strong reducing agents won't lead to a sudden detonation. And the decomposition of acetate wont create sulfur like in this experiment

      @@Linus-nq2op the sodium acetate will compose to ch4 and h2 at high temperatures. the sodium nitrate will probably compose to the nitite which explains the bubbles while melting. the nitrite is far more reactive and when the reaction starts the heat might release no2 + no and compose the sodium acetate which leads to a formation of a highly explosive (ch4+h2+nox can detonate in the right mixture) atmosphere above/around the compounds. this will happend in a very short amount of time which we will just recognise/see as a reaction of the solid/melted compounds with each other. thats just a therory but its plausible

    I guess the sodium acetate converts back to sodium carbonate when molten? I seem to think it has something to do with acids. I saw a video where they used vitamin c and sn. Think?
