Why is there no colour change when hydrogen peroxide and potassium iodide reacts?
When hydrogen peroxide and potassium iodide react, the iodide ions catalyze the decomposition of hydrogen peroxide into water and oxygen. The reaction does not result in a visible color change because no new colored species are formed during the reaction.
What is the elephant toothpaste recipe that includes potassium iodide?
To make elephant toothpaste with potassium iodide, mix hydrogen peroxide, dish soap, and food coloring in a container. In a separate container, mix water and potassium iodide. Then, pour the potassium iodide mixture into the hydrogen peroxide mixture and watch the foam erupt.
What gas is formed when KI is mixed with H2O2?
The hydrogen peroxide will decompose to give water and oxygen, potassium Iodide is acting as a catalyst2H2O2(l)-------------> 2H2O(l) + O2(g)
What is the reaction when hydrogen peroxide dish soap and potassium iodide are mixed together.?
When hydrogen peroxide, dish soap, and potassium iodide are mixed together, a foamy eruption occurs due to the decomposition of hydrogen peroxide into oxygen gas and water. The dish soap helps trap and stabilize the oxygen gas bubbles, creating a frothy foam. The potassium iodide acts as a catalyst, accelerating the decomposition reaction.
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 + H2O2>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 + O2So the overall reaction an be written as:H2O2 --KI--> H2O + O2
What is more unstable magnesium fluoride potassium iodide or hydrogen peroxide?
Hydrogen peroxide is the least stable.

Where does the potassium go in the potassium iodide catalyst reaction with hydrogen peroxide?
In the potassium iodide catalyst reaction with hydrogen peroxide, potassium iodide (KI) dissociates in solution to provide potassium ions (K⁺) and iodide ions (I⁻). The iodide ions act as a catalyst, facilitating the decomposition of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen gas (O₂). The potassium ions remain in the solution as spectators, balancing the charge but not participating directly in the reaction. Thus, the role of potassium in this context is primarily as a counterion.

Hydrogen Peroxide plus Potassium Iodide?
When hydrogen peroxide is added to potassium iodide, it rapidly decomposes into water and oxygen gas, producing a visible foaming reaction. This reaction is a decomposition reaction that is catalyzed by the presence of iodide ions.
What happened when you mix a solution of hydrogen peroxide and saturated potassium iodide with washing up liquid?
When a solution of hydrogen peroxide and saturated potassium iodide is mixed with washing up liquid, it produces oxygen gas rapidly due to the reaction between hydrogen peroxide and potassium iodide as a catalyst. The washing up liquid helps to trap the oxygen gas in the form of bubbles, creating a foamy reaction.
What is the list of catalysts commonly used in the decomposition of hydrogen peroxide?
Common catalysts used in the decomposition of hydrogen peroxide include manganese dioxide, potassium iodide, and iron(III) chloride.
How can I make elephant toothpaste using potassium iodide?
To make elephant toothpaste using potassium iodide, mix hydrogen peroxide with dish soap and food coloring in a container. Then, add potassium iodide to the mixture and watch as the foam erupts like toothpaste.
How can one effectively test hydrogen peroxide?
To effectively test hydrogen peroxide, you can use a chemical indicator like potassium iodide or potassium permanganate. When hydrogen peroxide is added to these indicators, it will cause a color change, indicating the presence of the compound. Additionally, you can also use a gas sensor to detect the release of oxygen gas when hydrogen peroxide decomposes.
