Ozone is determined quantitatively by first reacting it with excess of KI at a particular pH and then titrating the thus, liberated with a suitable titrant. The pH of the reaction and the titrant used in the titration are respectively.
Options:
Answer:
B
Solution:
When ozone is treated with excess of KI solution buffered with borate buffer ( pH 9.2 ), is liberated quantitatively which is titrated against a standard solution of using starch as an indicator and the amount of can thus be calculated.
