Question

Decomposition of H2O2( HYDROGEN PEROXIDE)can be prevented in presence of 1.Glycerol 2.acetanilide 3.phosphoric acid 4. all of these

Answer 1

4.All of these
Hope it helps!

Answer 2

‘Glycerol’, ‘acetanilide’ and ‘phosphoric acid’; all of these can be used to prevent the ‘decomposition of hydrogen peroxide’. Hence the correct answer is 4.  

‘Hydrogen peroxide’ is a very reactive chemical compound that can decompose to ‘water and oxygen gas’ under different conditions.  

To prevent this we can use glycerol, acetanilide and phosphoric acid as these compounds react with other atmospheric conditions and prevent the decomposition of hydrogen peroxide.
