AMMONIA. 99 



5. Amide of copper and nitrate of ammonium, Az H 2 Cu -f 

 (Az O 5 ) + (Az H 4 O) = 16. 



And so of the other compounds of metallic amides with salts 

 of ammonium. 



1. Oxamide, C 2 O 2 + Az H 2 = 5-5. 



This was the substance originally discovered by Dumas, which 

 led to the whole doctrine of amides. It is oxalate of ammonia 

 an atom of water 



2. Sulphamide, Az H 2 + SO 2 = 6. 



Discovered by Regnault Obtained by mixing chlorine gas, 

 sulphurous acid gas and olefiant gas. A liquid is formed which, by 

 a current of ammoniacal gas, is converted into a white powder 

 and sal-ammoniac. The white powder is sulphamide. 



3. Sulphohydramide, SO 3 + Az H 4 = 7-25. 

 The anhydrous sulphate of ammonia of Rose. 



4. Bisulphohydramide, 2 (S O 2 ) + Az H 4 = 10-25. 



The anhydrous acid sulphite of ammonia discovered by Rose. 



ii. AMMONIA, Az H 3 = 2-125. 



1. Liquid ammonia, Az H 3 -f 3 Aq. 



It dissolves oxides of zinc, copper, nickel, cobalt, &c. 



2. Ammoniated oxide of copper, 2 (Az H 3 ) -f- 3 (Ca O) -f- 6 

 Aq 26 (Kane.) 



A blue powder. 



3. Ammoniated oxide of mercury, Az H 3 -f 3 (Hg O) -f 3 



Aq 46 (Kane.) 

 And so of the other ammoniated oxides. 



1. Ammonietted chloride of sulphur, Az H 3 4- S Chi = 8-625 

 and 2 (Az H 3 ) + S Chi = 10-75. 



2. Ammonietted sesquichloride of phosphorus, 5 (Az H 3 ) -f 



(Ph Chl4) = 21-375. 



3. Ammonietted perchloride of phosphorus, 5 (Az H 3 ) -f Ph 



Chi 2 * = 23-875. 



4. Ammonietted chloride of boron, 3 ( Az H 3 ) + 2 (Bo Chi 1 *) 



= 15-125. 



5. Ammonietted perchloride of tin, Az H 3 + 2 (St Chi 2 ) = 



18-375. 



6. Ammonietted chloride of calcium, 4(AzH 3 )+Ca Chl=15*5. 



7. Ammonietted chloride of strontium, 4 (Az H 3 ) -f Str Chi 



= 18-5.
