Zeisel's method is a specific quantitative technique used for the estimation of alkoxy (e.g., methox — Practical Organic Chemistry and Purification Chemistry Question

💡 Solution & Explanation

In Zeisel's method, the ether bond is cleaved using hot, excess $HI$. This forms $CH_3I$, which is distilled off and trapped in an alcoholic $AgNO_3$ solution, precipitating quantitative amounts of $AgI$. One mole of $AgI$ perfectly correlates to one mole of methoxy group.
