When H2O2 is added to TiO2 solution acidified with conc. H2SO4, the orange coloured compound formed is
Ti2O3
H2Ti2O8
H2TiO3
H2TiO4
TiO2 + 2H2SO4 → Ti(SO4)2 + 2H2O
Ti(SO4)2 + H2O2 + 2H2O → H2TiO4 + 2H2SO4
An orange coloured solution acidified with H2SO4 and treated with a substance'X' gives a blue coloured solution of CrO5 .The substance 'X' is :
Hydrogen peroxide is detected by using acidified TiO2. An orange coloured compound (B) is formed. The change in oxidation state of ‘Ti’ in this reaction is:___
