Because liver has more catalase than potatoes.
No, it is not safe to use hydrogen peroxide as a preservative for milk. Hydrogen peroxide is a strong oxidizing agent and can cause harm if consumed in high concentrations. It is not approved or recommended for use in preserving food items, including milk.
There is no reaction between H2O2 and K2Cr2O7 because both are oxidants.
Temperature
endothermic because it absorbs energy, and not releasing it
The false positive from the reaction of hydrogen peroxide and the inoculating loop would be caused by poor specificity. The formula for specificity is TN/TN+FP.
The substance that changes is the hydrogen peroxide. After it reacts, it forms bubbles of oxygen and water.
AR is analytical reagent and LR laboratory reagent; practically differences are not significant and depends on the reagents company.
reaction betwen sodiumbisulphite and hydrogen peroxide
They are the same chemical.
The difference between 6%, 9%, and 12% Hydrogen Peroxide solution is the Hydrogen content.
Hydrogen peroxide may be represented as H2O2 or HO-OH, with contrast to normal oxides the oxidation number of oxygen in peroxide is -1.
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.
yes
between 2,5 and 4,5
The white you see is many microscopic bubbles of oxygen released by a reaction between the Hydrogen Peroxide (H2O2) and your saliva.
Hydrogen Peroxide decomposes in oxygen gas and water.
Hydrogen peroxide has covalent bonds between the atoms. The atoms are held together by those covalent bonds. There are van der Waals and dipole-dipole forces between the molecules.
