It is estimated with the help of potassium iodide , when ozone and potassium iodide react, iodine is liberated, now this iodine is titrated against a stand solution of sodium thiosulphate using starch as an indicator.

The quantitative estimation of ozone gas can be done idiometrically l.when ozone is treated with exess of potassium iodide, bufferred with a borate buffer(pH=9.2), iodine is liberated which can be titrated against a standard solution of sodium thiosulphate.
2I+H2O+O3------>2OH+I2 +O2
Iodine liberated is titrated against a standard hypo(sodium thiosulphate) slution using such as an indicator.
2Na2S2O3 +I2------>Na2S4O6+2Nacl

Dear student,
Please find the answer to your question.
 
The quantitative estimation of ozone gas can be done idiometrically.
When ozone is treated with exess of potassium iodide, bufferred with a borate buffer(pH=9.2), iodine is liberated.
2I + H2O + O3 → 2OH  + I2 + O2
The Iodine liberated is titrated against a standard hypo(sodium thiosulphate) slution using starch as an indicator.
2Na2S2O3 + I2 → Na2S4O6 + 2NaCl
 
Thanks and regards,
Kushagra
