Why conc `"H"_(2)"SO"_(4),"P"_(4)"O"_(10)` and anhydrous `CaCl_(2)` cannot be used to dry ammonia ? (Hint : ammonia reacts with them forming `(NH_(4))_(2)SO_(4),(NH_(4))_(3)PO_(4)" and "CaCl_(2),8NH_(3)`)

Text Solution

Verified by Experts

For drying ammonia quick line (CaO) is used.
`to` For drying ammonia conc. `H_(2)SO_(4),P_(4)O_(10)` and anhydrous `CaCl_(2)` cannot be used because they react with ammonia and forms `(NH_(4))_(2)SO_(4),(NH_(4))_(3)PO_(4)` and `CaCl_(2).8NH_(3)`
`H_(2)SO_(4)+2NH_(3)to(NH_(4))_(2)SO_(4)`
`P_(4)O_(10)underset(H_(2)O)overset(NH_(3))to(NH_(4))_(3)PO_(4)`.
`CaCl_(2)+8NH_(3)toCaCl_(3)8NH_(3)`.
