Nothing, they don't react with each other: K + Au --> 0
When potassium reacts with oxygen, it forms potassium oxide (K2O). The reaction is highly exothermic and produces a bright flame due to the high reactivity of potassium with oxygen. Potassium oxide is a white solid that can react further with water to form potassium hydroxide.
Nothing happens. Gold will not react with sulfuric acid.
When iron ions react with potassium permanganate, the iron ions are oxidized, and the potassium permanganate is reduced. The overall reaction results in the formation of iron(III) ions and manganese dioxide.
Gold does not react with water under normal conditions. Gold is a noble metal and is highly unreactive with most substances, including water.
Silver does not react with potassium nitrate under normal conditions. Potassium nitrate is a relatively stable compound that is typically used as a fertilizer or in fireworks, and it does not react with silver.
Copper metal is less reactive than potassium so it will not react with potassium cyanide.
When potassium reacts with oxygen, it forms potassium oxide (K2O). The reaction is highly exothermic and produces a bright flame due to the high reactivity of potassium with oxygen. Potassium oxide is a white solid that can react further with water to form potassium hydroxide.
Nothing happens. Gold will not react with sulfuric acid.
Silver iodide (AgI), a precipitate insoluble in water, don't react with potassium nitrate.
Nothing happens because gold doesn't react with sulfuric acid.
When iron ions react with potassium permanganate, the iron ions are oxidized, and the potassium permanganate is reduced. The overall reaction results in the formation of iron(III) ions and manganese dioxide.
The gold will sink, nothing more. It will not dissolve or react in any way.
Gold does not react with water under normal conditions. Gold is a noble metal and is highly unreactive with most substances, including water.
Iron does not react with potassium hydroxide under normal conditions because iron is a less reactive metal compared to potassium. Potassium hydroxide is a strong base that can react with more reactive metals such as aluminum and zinc, but typically not with iron.
Silver does not react with potassium nitrate under normal conditions. Potassium nitrate is a relatively stable compound that is typically used as a fertilizer or in fireworks, and it does not react with silver.
Potassium is an alkali metal !
When potassium and iodine react, they form potassium iodide. The ions involved are K+ (potassium ion) and I- (iodide ion).
