會即刻爆炸架......唔會有片你睇

樓下位朋友...我諗你真係要睇清楚佢係講緊HCl acid...Potassium 放落水已經係激烈反應 (最尾位朋友俾左youtube link)Potassium放落 HCl Acid 係會即爆...你上堂睇既係放落水...諗清楚至講, ok?

爆炸,,
since K is an very reactive element,
if you add K into water, it will move very fast in the water surface ,
it is very dangerous for you to add K into HCL, as explosive will happen

It will explode due to the release of hydrogen gas and heat in a short time.

Then aqueous KCl will be formed.

Sorry, crystal of KCl and steam will be formed due to crystallization because of high temperature.

2006-12-08 23:17:29 補充:
Hydrogen is also released at first. But then it reacts with oxygen to give steam due to high temperature. When the two gases react with each other, explosion occurs.

2006-12-08 23:24:16 補充:
The 'two gases' are hydrogen and oxygen.Large amount of initial heat is produced because potassium displaces hydrogen ion very quickly.And the initial heat causes the 'two gases' to react.

It won't 'blow up' as such - but it will give out alot of heat and a gas (H2) and a white ppt KCl once all the water has been evaporated. There might be a video on the web because I've since something like that before, but in class.
It won't blow up because K isn't as reactive as something like Cs anf Fr - those will definitely blow up with a huge fire ball!

Can people be a bit more specific about the term 'explosion'?? A huge one or just a mini one? The term is quite misleading and most people tended to think BIG ones when they read, which is not true.

Ai!! I'm an idiot...I managed to read the question TWICE with H2O in mind! Too much work and not enough sleep in the lab I guess - please disregard me answer as it only applies to water. Extremely sorry...
