Question

hydrogen peroxide on treatment with an acid solution of titanium salt gives

Answer 1

this answer of your question is blue

Answer 2

Reaction of hydrogen peroxide with titanium has been investigated over the range of pH 0 to 13. Below pH 2 this reaction gives orange-colored ion-species, [Ti(OH)2(H2O)(H2O2)]2+ or (TiO2·-aq)2+. In the range of pH 3 to 6 formation of a yellow sandeis observed and its chemical formula is presumed to be [Ti(OH)3(H2O2)]+. Existence of a species different from the above is indicated by the pale yellow color observed in the region of pH 7 to 9. This species is very unstable unless a large excess of hydrogen peroxide is present.
