Alkali Metals In A Water/Alcohol Solution - Powerful Exothermic Chemical Reaction!

Описание

You may have seen what happens when you drop alkali metals in water, but as far as I know, a mix of water and alcohol has never before been used for this experiment and the results went about as expected for two of them. The lithium reacted with the water as lithium normally does and never ignited the mixture, the sodium performed the most impressively of the three, lighting it on fire and I actually had to blow out the alcohol fire myself, the potassium did about as expected but was actually less impressive than sodium. This time around, I did not do rubidium for safety reasons, but I wanted to show in general how alkali metals react to an alcohol and water mixture. Here is a quick review for those who didn't see the initial experiment, the formula for the reaction of alkali metals and water, M representing metal in this case (plug in any alkali metals for this to work).

M + H2O → MOH + 1/2H2

Alkali metals in water produce an exothermic reaction, meaning they produce heat. Hence why I figured it'd light on fire. The amount of heat was beyond the ignition temperature of alcohol.

I have some alkali metals left over and I may do more experiments if this is a success. Let me know what you'd like to see or just an entirely different type of science experiment and I'll try to do it. I appreciate each and every one of you watching and leaving comments. Sharing my videos also helps a lot. In this I use lithium, sodium, and potassium, no rubidium, and absolutely no cesium. It's obvious also why I have no francium, it's too expensive to buy. Please DO NOT attempt at home!
