A text-book on chemistryFor the use of schools and colleges . AQUA AMMONIA. 307 as is represeentd in Fig. 280. The water will take it p Fig. up until its specific gravity is lowered to .875. It thencontains 32J per cent, of gas. At .900 it contains 26per cent.; at .951, per cent.; at .969, per solution is much used for precipitating an^d neutral-izing. It affords the best means of obtaining ammonia,merely requiring to be warmed in a flask, when the gasreadily comes off.

Ammonium, Am-=iNII±=.\% is a hypothetical body, believed to be of a metallic na-ture; its symbol is Am. It may be combined withmercury by decomposing a solution of an ammoniacalsalt by a Voltaic current, the negative pole being incontact with a globule of that metal, or by putting anamalgam of potassium and mercury in a solution of salammoniac. Under those circumstances the mercuryswells, and eventually becomes of a soft consistency,like butter, preserving its metallic aspect the mercury increases to thirty times its volumeat 100°, it increases in weight only ^oVo-th Part- All at-tempts to separate the ammonium from this
