When Potassium is put in water, it reacts vigorously. It sends out a purple flame and it makes a small explosion. You can also smell the smell of burnt fumes.
No, they do not
Potassium react violent with water, iron react only if oxygen is present.
You get a mixture of potassium and magnesium. They're metals; they don't react with each other.
Yes, they react tor form water and the corresponding potassium carboxylate salt.
No. Potassium will react violently on contact with water. Potassium is stored under oil to protect it from air and water.
potassium hydroxide
potassium hydroxide+hydrochloricacid =potassium chloride + water .
Not safely. If potassium makes contact with water it react violently, bursting inflames and possibly exploding.
When potassium reacts with water the potassium burns a bright purple light, a gas is given off with a hissing noise and the potassium rockets around the surface of the water because it floats.
There should be Silver nitrate dissolved in the water, only then it can react
Not with water! Maybe with something else in the water? It only ionises when dissolved in the water to: K+ and Br- , but does not react with it. Dissolving is purely physical!
The bronze and silver stars will react with water, eventually. Since I think you mean "metals", how about sodium and potassium?
