Tardigrade Admin · Accepted Answer

2KI + H2O + O3 arrow 2KOH + I2 + O2

Q. Estimation of ozone can be made quantitatively by:

decomposition into $O_{2}$ and absorption of $O_{2}$ into pyrogallol

volumetric method using $K I$ and titration of the liberated iodine using hypo solution

oxidative ozonolysis method

all methods given above

$2 K I + H_{2} O + O_{3} \to 2 K O H + I_{2} + O_{2}$

Q. Estimation of ozone can be made quantitatively by:

decomposition into O2​ and absorption of O2​ into pyrogallol

volumetric method using KI and titration of the liberated iodine using hypo solution

oxidative ozonolysis method

all methods given above

2KI+H2​O+O3​→2KOH+I2​+O2​

decomposition into $O_{2}$ and absorption of $O_{2}$ into pyrogallol

volumetric method using $K I$ and titration of the liberated iodine using hypo solution

$2 K I + H_{2} O + O_{3} \to 2 K O H + I_{2} + O_{2}$
