When potassium is dropped into aqueous zinc nitrate zinc and aqueous potassium nitrate form.?
Yes, when metallic potassium is added to an aqueous solution of zinc nitrate, a single replacement reaction occurs. The potassium replaces the zinc in the compound to form potassium nitrate and zinc metal. This reaction is represented by the chemical equation: 2K(s) + Zn(NO3)2(aq) -> 2KNO3(aq) + Zn(s)
What will happen if small piece of crystall of potassium permaganate is dropped in a beaker filled with water and is heated?
When a small piece of potassium permanganate crystal is dropped into water and heated, it will dissolve and release potassium ions and permanganate ions into the solution. As the temperature increases, the rate of dissolution will also increase, leading to a faster dispersal of the ions. The purple color associated with potassium permanganate will be more pronounced as more of it dissolves.
When Sodium ignites when dropped in water is it either a physical property or a chemical property?
i am asking the same quesion it is on my chemistry homework and i dont know the answer!!
What gas is produced when calcium metal is dropped into water?
Hydrogen gas. Ca + 2H2O ------> Ca(OH)2 + H2
Can silver potassium cyanide kill you?
Let's clear one thing up first: potassium cyanide is a solid (powder). At room temperature, in its pure form, it can't be drunk.Of course, one can take a tablespoon of potassium cyanide and dissolve it in a glass of water, THEN drink the resulting solution. The result would be a quick DEATH, because there is more than a fatal dose of cyanide in one tablespoon of the compound.The gas chamber, which was used as an execution method by some US states until quite recently, makes use of potassium cyanide. Pellets or powdered potassium cyanide are dropped into a dish filled with sulfuric acid, which is placed underneath the chair of the condemned prisoner. The potassium cyanide quickly reacts with the acid, and releases hydrogen cyanide, which is the gas that poisons and kills the prisoner.Potassium cyanide is a common and useful laboratory chemical, despite its toxicity. As with all laboratory chemicals, it should be used with care and respect.
When a small piece of potassium metal is dropped into a breaker of water the potassium moves about rapidly and then ignites within seconds the metal is gone and all activity ceases this is and example?
It is an example of a chemical reaction
What is the chemical formula of the salt produced by the neutralization of potassium hydroxide with nitric acid?
Potassium Nitrate+Water HNO3 (aq)+KOH (aq)-->KNO3 (aq)+H2O (l)
What happens to the ions when potassium permanganate are dropped into water?
When potassium permanganate is dropped into water, the ions are solvated by the water molecules. This results because potassium permanganate is water soluble. Thus, the solid compound is separated into aqueous ions.
When potassium is dropped into aqueous zinc nitrate zinc and aqueous potassium nitrate form.?
Yes, when metallic potassium is added to an aqueous solution of zinc nitrate, a single replacement reaction occurs. The potassium replaces the zinc in the compound to form potassium nitrate and zinc metal. This reaction is represented by the chemical equation: 2K(s) + Zn(NO3)2(aq) -> 2KNO3(aq) + Zn(s)
If a piece of potassium metal is dropped in water then a vigorous reaction takes place with the formation of potassium hydroxide and hydrogen gas is evolved?
Yes, it is correct.
Which substance turns yellow when nitric acid is dropped on it?
Potassium iodide turns yellow when nitric acid is dropped on it due to the formation of elemental iodine.
Chemical equation potassium and water?
2K(s) + 2H2O(l) -> 2KOH(s) +H2(g) However, if potassium were dropped into water, there would be so much water that the KOH would not be solid but aqueous so it should read 2K(s) + 2H2O(l) -> 2KOH(aq) +H2(g)
Why boiling water is used instead of cold water when potassium manganate is dropped in the boiling water?
Potassium Manganate (VII) also called potassium permanganate, dissolves very quickly in hot water and much slower in cold water.
Was potassium ever included in bombs dropped on Germany in World War 2?
No. while metallic potassium reacts violently with water, it is mild compared to explosives such as TNT. Incendiary weapons may include phosphorus and reactive metals, such as aluminum or magnesium- but not potassium.

Is food color is dropped into water to give it color a chemical change?
no, a physical change
What happen if the potassium permanganate solution drop to the water?
If potassium permanganate solution is dropped into water, it will dissolve and create a purple or pink solution. Potassium permanganate is a strong oxidizing agent and can be used for various applications such as disinfection and water treatment.
