If you remember high school chemistry class at all, you might remember what happens when you drop potassium and sodium into water: It creates a big flashing, sparking explosion and remains a classic ...

Potassium reacts quickly with water producing a lilac-coloured flame For example, when potassium is added to water, the metal melts and floats. It moves around very quickly on the surface of the water ...

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 ...

An international team of researchers have, for the first time, glimpsed the ultrafast process of proton transfer following ionization of liquid water, shedding light on how radical cations separate ...

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 ...

Do only potassium ions pass through the selectivity filter of a potassium channel, or are there water molecules between the ions? This question has been a source of controversy for years. Researchers ...

Note that you are expected to know some of the key safety points for these reactions. These include: use of a plastic safety screen using small pieces of the metal using a large volume of water using ...
