What will happen when potassium iodide react with hydrogen per oxide?

This reaction decomposes Hydrogen peroxide into Water and Oxygen: Here is the stepwise process:
1> Hydrogen peroxide oxidizes the Potassium iodide into another salt called Potassium Hypoiodite, and itself gets reduced to water.
H2O2 + KI----> KIO + H2O
2>This salt is quite unstable and rapidly reacts with Hydrogen peroxide. Here the Peroxide ions disproportionates into Oxide ions and Molecular Oxygen gas.
H2O2 + KIO ----> KI + H2O + O2
So the overall reaction an be written as:
H2O2 --KI--> H2O + O2

What happen when metal is added to water?
it depends what metal it is, if it is a reactive metal like potassium or sodium it will effervesce (bubble) and create a metal hydroxide and hydrogen. if it is a less reactive metal it will create a metal oxide and hydrogen (zinc, etc)
What is the formula for potassium and oxygen to give potassium oxide?
K2O is potassium oxide
Why potassium iodate is added to potassium iodide in iodometry titration?
Iodometric titration means the titration of triiodide. Preparation of triiodide can be prepared by adding solid iodine to excess potassium iodide, however since iodine sublimes it is more difficult to weigh than potassium iodate. The triiodide would then need to be standardized with primary standard grade arsenious oxide. A better way is to weigh potassium iodate and add to a small excess of potassium iodide. The two ions (iodide and iodate) will also form the needed triiodide in an acidic environment. If the reagent is made fresh this way it can be used to standardize thiosulfate. Iodide iodate of known normality can also be used to titrate unknown concentrations of sulfite. For example, steam boiler treatment applications.
Is potassium oxide soluble?
Potassium oxide reacts with water to form soluble potassium hydroxide.
What is the name of k2O?
K2O2 is the molecular formula for the compound potassium peroxide. Since both potassium (K) and oxygen (O) have a subscript of "2", a potassium peroxide molecule contains two potassium atoms and two oxygen atoms.
How many elements are there in potassium oxide?
There are 2 elements in potassium oxide, which are potassium and oxygen.
Water reacting with potassium oxide to form potassium hydrogen?
K2O + H2O --> 2K+ + 2OH- The water turns to basic.
What will happen if hydrogen gas is heated over copper oxide?
the copper oxide will turn red
What happen when metal is added to water?

What is the formula for potassium and oxygen to give potassium oxide?
K2O is potassium oxide
Is potassium oxide polor or nonpolar?
Yes, because it is a charged species (ion) composed of two or more atoms acting as a single unit.
What elements are in potassium oxide?
Potassium oxide (K2O) is composed of potassium and oxygen. The answer is in the name!
What are the elements in potassium oxide?
Potassium oxide (K2O) is composed of potassium and oxygen. The answer is in the name!
Example of inorganic compound?
sodium chloride - NaCl, uranium tetrafluride - UF4, potassium iodide - KI, hydrofluoric acid - HF, zirconium oxide - ZrO2, harfnium oxide - HfO2, calcium sulphate - Ca SO4
What is the chemical formula for potassium hydrogen sulfide?
Potassium hydrogen sulfide is KHS. (In KHS or KSH you could replace an S by an O atom to get KOH called hydro-oxide or shortened hydroxide)
