Question

An indicator ' X ' is used for studying the effect of variation in concentration of iodide on the rate of reaction of iodide ion with H 2 O 2 at room temp. The indicator ' X ' forms blue colored complex with compound ' A ' present in the solution. The indicator ' X ' and compound ' A ' respectively are (A) Starch and iodine (B) Methyl orange and H 2 O 2 (C) Starch and H 2 O 2 (D) Methyl orange and iodine

I -+ H 2 O 2 longrightarrow underset(A)I 2+ H 2 O I 2+ underset text (Indicator) text Starch longrightarrow text Blue

Starch and iodine

Methyl orange and $H_{2} O_{2}$

Starch and $H_{2} O_{2}$

Methyl orange and iodine

$I^{-} + H_{2} O_{2} ⟶ (A) I_{2} + H_{2} O$
$I_{2} + (Indicator) Starch ⟶ Blue$

Starch and iodine

Methyl orange and H2​O2​

Starch and H2​O2​

Methyl orange and iodine

I−+H2​O2​⟶(A)I2​​+H2​O I2​+ (Indicator) Starch ​⟶ Blue

Methyl orange and $H_{2} O_{2}$

Starch and $H_{2} O_{2}$

$I^{-} + H_{2} O_{2} ⟶ (A) I_{2} + H_{2} O$
$I_{2} + (Indicator) Starch ⟶ Blue$
