1.	The amount ozone in a gas mixture may be determined by passing the gas into a `"_____"` solution buffered with a borate buffer (pH 9.2).A. `KI_(3)`B. `KIO_(3)`C. `KI`D. `KIO_(4)`
Answer» Correct Answer - 3 When ozone reacts with an excess of potassium iodide solution buffered with a borate buffer (`pH9.2)`, iodine is liberated which can be titrated against a standard solution of sodium thiosulphate: `O_(3)+2K^(+)+2I^(-)+H_(2)O rarr I_(2)+2KOH+O_(2)` This is a quantitative method for estimating `O_(3)` gas.
