Question
If an organic compound containing carbon and hydrogen is completely combusted over $CuO$, what is the specific chemical role of passing the resultant gases through a U-tube containing anhydrous magnesium perchlorate?
Answer: B
💡 Solution & Explanation
Anhydrous magnesium perchlorate ($Mg(ClO_4)_2$) is an excellent desiccant. In quantitative analysis, it is used as an alternative to anhydrous $CaCl_2$ specifically to absorb the $H_2O$ vapor produced from the combustion of hydrogen in the organic compound.
