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.
Гидрид натрия (реакция гидрида натрия с водой и горение на воздухе) 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. |
