Alkali metals can react explosively with water and it is textbook knowledge that this vigorous behaviour results from heat release, steam formation and ignition of the hydrogen gas that is produced.
For decades, science enthusiasts have delighted at the famously energetic way sodium and potassium explode on contact with water. Researchers in Europe now show that the long-accepted explanation for ...
The spectacular reaction of alkali metals with water was poorly understood — despite being a staple of chemistry classes. It’s the classic piece of chemical tomfoolery: take a lump of sodium or ...
The golden metallic water layer on a sodium-potassium alloy drop. Courtesy: Phil Mason A metallic water solution has been observed in the laboratory for the first time thanks to a new method that ...
When a chunk of alkali metal gets tossed into water, it explodes. But when a team of scientists gently placed a liquid drop of a sodium-potassium alloy on top of a water surface, they observed a ...
When a small piece of sodium is placed in a petri dish with water and phenolphthalein, the sodium becomes a molten ball and darts around the dish, leaving a pink trail. The reactions of potassium, ...
Even if you slept your way through high school chemistry, there was typically one day that ensured you were awake. That’s when, after an extensive safety lecture, the teacher brought out the alkali ...
