Ammonia Gas: Preparation, Properties, uses
<p>In the laboratory, <a href="https://www.chemistrypage.in/ammonia-gas/" rel="noopener ugc nofollow" target="_blank">ammonia</a> is made by heating the ammonium chloride with a quenched lime.</p>
<p><strong>2NH4Cl + Ca(OH)2 → CaCl2 + 2H2O + 2NH3</strong></p>
<p>In a rigid glass tube, a mixture of ammonium and quenched lime is heated. The received <a href="https://www.chemistrypage.in/ammonia-gas/" rel="noopener ugc nofollow" target="_blank">ammonia gas</a> is collected from the gas jar by downward displacement of air.</p>
<p>Before being collected in a gas jar, it is passed onto CaO, which removes the moisture of this gas.</p>
