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.
How H2O different from H2O2?
H2O is water which is formed from a covalent bond between hydrogen and oxygen. H2O2 is hydrogen peroxide which is formed from an ionic bond between the hydrogen H+ cation and the peroxide O2- anion.
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)
Is H2O2 a chemical compound or an element?
H2O2 is a chemcial COMpound. It is formed from atoms of the elements oxygen and hydrogen combining together. H2O2 is hydrogen peroxide. Structure is H-O-O-H Compare with H2O is water . Structure is H-O-H
Why does hydrogen peroxide hiss when it is left sealed for a long time and then opened?
The hissing sound when opening a bottle of hydrogen peroxide that has been sealed for a long time is due to the release of oxygen gas. Over time, hydrogen peroxide can break down into water and oxygen, resulting in a build-up of gas inside the bottle. When the bottle is opened, the gas is released, creating the hissing sound.
What does 20 volumes hydrogen peroxide mean?
This means that for every volume of hydrogen peroxide used, 20 volumes of oxygen will be produced. For example, if 1 ml of hydrogen peroxide is used/decomposes, 20 ml of oxygen will be formed.
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.
Formed by combining the elements hydrogen and oxygen?
h2o is water h2o2 is hydrogen peroxide
Does sunlight help form hydrogen peroxide in rainwater?
Sunlight will degrade any hydrogen peroxide that is in the water. This is why over-the-counter hydrogen peroxide is sold in brown bottles.
If oxygen reacts with hydrogen what do you get?
Water , however if there is insufficient oxygen some hydrogen peroxide is formed, (H2O2 )
How H2O different from H2O2?
H2O is water which is formed from a covalent bond between hydrogen and oxygen. H2O2 is hydrogen peroxide which is formed from an ionic bond between the hydrogen H+ cation and the peroxide O2- anion.
What might be formed in the chemical reaction H202?
H2O2 is not a chemical reaction, it is Hydrogen Peroxide.
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 product of Fentons reagent with silver?
The reaction product of Fenton's reagent (a solution of hydrogen peroxide and ferrous iron) with silver is typically silver oxide (AgO) or silver hydroxide (AgOH) depending on the conditions of the reaction. These products are formed when the silver ions present in the solution react with the hydroxyl radicals generated by Fenton's reagent.
Do an element molecule compound or mixture explain when 2 oxygen atoms bond chemically with 2 hydrogen atoms and hydrogen peroxide is formed?
1. Hydrogen peroxide is a chemical compound.2. Because the direct method of preparation is not possible hydrogen peroxide is obtained from oxygen and hydrogen by the intermediate of antraquinone, using a palladium catalyst.
Oxygen gas can be formed by using what compound in the presence of manganese dioxide?
Hydrogen peroxide (H2O2)
Is Hg2O2 the formula for Mercury peroxide?
This formula, if the compound exists, is the formula for mercury(I) peroxide. The formula for mercury(II) peroxide would be HgO2.
