When potassium hydroxide (KOH) is mixed with hydrochloric acid (HCl), a neutralization reaction occurs. This reaction forms potassium chloride (KCl) and water (H2O). The products of this reaction are a salt (KCl) and water.
When potassium manganate is mixed with water, it dissolves to form a purple solution. Over time, the solution may slowly turn colorless as the potassium manganate reacts with water and other substances present in the solution.
Any reaction occur.
When potassium permanganate is mixed with water and glycine, a reaction may occur in which the permanganate oxidizes the glycine. This can result in the production of manganese dioxide, water, and carbon dioxide. The specific products and reaction conditions will depend on the concentrations and proportions of the reactants. It is important to handle potassium permanganate with care as it is a strong oxidizing agent.
When potassium reacts with water, it forms potassium hydroxide and releases hydrogen gas. When potassium reacts with oxygen, it forms potassium oxide.
I have no idea. The products of that reaction are water (not a gas at room temperature) and potassium chloride (not a gas at room temperature).
When chlorine is mixed with potassium bromide solution, chlorine will displace bromine to form potassium chloride. Similarly, when chlorine is mixed with potassium iodide solution, chlorine will displace iodine to form potassium chloride. These reactions are examples of displacement reactions where a more reactive element displaces a less reactive element from its compound.
The potassium catches on fire and then explodes. Seriously. Don't try it.
When potassium hydroxide and hydrochloric acid are mixed, the salt potassium chloride is formed. This chemical reaction also produces water.
nothing happens
When oxygen is mixed with potassium, it can react vigorously, sometimes even explosively. This reaction forms potassium oxide, which is a white powder, and releases a large amount of heat. This kind of reaction is highly exothermic and needs to be handled with caution.
