Quantitatively, ozone can be estimated with the help of potassium iodide. When ozone is made to react with potassium iodide solution buffered with a borate buffer (pH 9.2), iodine is liberated. This liberated iodine can be titrated against a standard solution of sodium thiosulphate using starch as an indicator.
How was ozone estimated quantitatively?
We have to know that ozone may be measured quantitatively using potassium iodide. Iodine is released when ozone reacts with potassium iodide solution buffered with a borate buffer (pH 9.2). ... Sodium thiosulphate reacts with iodine to give sodium tetrathionate which is quantitatively estimated for ozone estimation.
How is O3 estimated quantitatively write chemical equation?
Answer: Estimation of O3 is done by treating it with excess of KI solution buffered with borate buffer (pH 9.2) when I2 is liberated quantitatively. 2l? (aq) + H2O (l) + O3 (g) 2OH? (aq) + I2 (s) + O2(g) The I2 thus liberated is titrated against a standard solution of sodium thiosulphate using starch as indicator.
