字幕表 動画を再生する 英語字幕をプリント Hello everyone today We'll find out what happens when you combine two active alkali metals, for this I took a piece of sodium and potassium and began to rub them against each other within the evaporating dish to provide the alloy from oxidation by being exposed to Air [I've] Decided to conduct the melting [of] sodium and potassium under a layer of Kerosene since potassium is a very soft metal it immediately deforms and wrinkles over. Overtime, a liquid array of sodium and potassium is formed as a point of contact of the two metals Which is instantly being covered by Gray oxide [film] this [alloy] remains in liquid state from minus 20 [to] plus 785 degrees Celsius, it's a very dangerous alloy because it's more active than sodium or potassium in the round I Fill in the syringe with a little bit of alloy alloy has a glassy surface inside the syringe such as mercury. Now I'm dripping stored in potassium all into the water As can be seen, [color] instantly ignite in water forming burning droplets. If you drop this alloy on the wet surface the alloy will also light up, sometimes with an explosion Its then I pour in the remaining alloy into the water Sodium potassium alloy is used in Nuclear reactors as coolant as Well in metallurgy subscribe to my channel to see many more new and interesting experiments Pull that trigger right from your face Wow, he'll be all right
