Suggests method for the quantitative estimation of ozone (O_3). – InterviewSolution

1.	Suggests method for the quantitative estimation of ozone (O_3).
Answer» Solution :When `O_3` is treated with excess potassium iodide solution containing a borate buffer having pH = 9.2, IODINE is liberated.`2l^(-)+H_2O+O_3to2OH^(-)+l_2+O_2` The iodine thus liberated is titrated against STANDARD sodium THIOSULPHATE solution. From the, titre value, theamount of `O_3` present can be estimated.
