Sodium hydride (reaction of sodium hydride with water and combustion in air)

Several years ago, an elderly friend retired from the laboratory. I was asked to master the remaining "inherited" reagents. I presented some photos of the reagents in factory packaging on the topic "Photos of reagents" on the forum. Among others, I came across a plastic bottle with light grey powder and the inscription "NaH 90%". I took a sample of the powder from above and added it to water - the solution became alkaline. I decided that the reagent had deteriorated over many years due to air moisture, so I used it for washing dishes. Once again, when added to water, I observed a flash - only the top layer deteriorated.

I decided to make a video of two experiments. When the powder burns in the air, you may notice the formation of sodium droplets for some time.



Гидрид натрия (реакция гидрида натрия с водой и горение на воздухе)
Несколько лет назад один пожилой товарищ уволился из лаборатории. Мне было предложено освоить оставшиеся "в наследство" реактивы. Некоторые в заводской фасовке я представлял в теме "Фото реактивов". Среди прочих попался полиэтиленовый пузырек со светло-серым порошком и надписью "NaH 90%". Пробу порошка взял сверху, добавил в воду - раствор приобрел щелочную реакцию. Решил, что за многие лета реактив испортился от влаги воздуха, поэтому использовал его для мытья посуды. В очередной раз при добавлении в воду наблюдал вспышку - испортился только верхний слой.

Решил снять видео двух экспериментов. При горении порошка на воздухе можно заметить образование капель натрия на некоторое время.
