In Aluise's method for the direct estimation of oxygen in an organic compound, the carbon monoxide ( — Practical Organic Chemistry and Purification Chemistry Question
Question
In Aluise's method for the direct estimation of oxygen in an organic compound, the carbon monoxide ($CO$) formed is quantitatively oxidized to $CO_2$ using which of the following specific reagents?
Answer: B
💡 Solution & Explanation
In Aluise's method, the organic compound is heated in a stream of nitrogen. The oxygen forms $CO$ over red-hot coke. This $CO$ is then oxidized to $CO_2$ by passing it through warm iodine pentoxide ($I_2O_5$), releasing $I_2$. The mass of $CO_2$ is used to calculate the oxygen percentage.
