Specific test for the detection of H(2)O...

Specific test for the detection of `H_(2)O_(2)` is

A

Reaction with acidified `TiO_2`

B

Starch Iodide paper into blue

C

Conversion of `PbO_2` into yellow colour

D

Conversion of black PbS into `PbSO_4`

Text Solution

Verified by Experts

The correct Answer is:
A
`H_2O_2` gives orange colour (pertitanic acid) on reaction with acidified titanium dioxide.
`TiO_2 + 2H_2SO_4 to Ti(SO_4)_2`
` + 2H_2O overset(H_2O_2) to underset("pe ti tan ic acid")(H_2TiO_4 + 2H_2SO_4)`
