Introduce the benzoic acid residue as the sodium salt into a boiling-tube and heat in a beaker of boiling brine until the liquid is driven off and all drops of condensation water have disappeared. Cool, add 0 1 g of potassium nitrate and 1 ml of concentrated sulphuric acid. Place the tube in boiling water for twenty minutes. Cool and add 2 ml of water. Hold the tube under running water and add carefully 10 ml of 15 per cent ammonia solution followed by 2 ml of a 2 per cent hydroxylamine hydrochloride solution. Mix well and place in a beaker of water at 65° for five to six minutes. Cool and match the colour with that developed by mixing the amounts of iron ammonium alum and potassium thiocyanate solution given below for varying quantities of benzoic acid.

Chlorides, bromides, and iodides can be quantitatively determined by treatment with silver nitrate, and, with suitable precautions, the precipitated halide is washed, dried, and weighed. Chlorides in neutral soln. can be determined by F. Mohr s volumetric process 27 by titration with a standard soln. of silver nitrate with a little potassium chromate or sodium phosphate as indicator. When all the chloride has reacted with the silver nitrate, any further addition of this salt gives a yellow coloration with the phosphate, and a red coloration with the chromate. In J. Volhard s volumetric process, the chloride is treated with an excess of an acidified soln. of silver nitrate of known concentration. The excess of silver nitrate is filtered from the precipitated chloride, and titrated with a standard soln. of ammonium thiocyanate, NH4CN8—a little ferric alum is used as indicator. When the silver nitrate is all converted into thiocyanate AgN03-fNH4CNS=AgCNS +NH4NOS, the blood-red coloration of ferric thiocyanate appears. 

Yolumetrically, thiocyanate is estimated by Volhard s method, which involves titration with standard silver nitrate solution containing nitric acid, ferric alum being used as indicator. Cuprous thiocyanate dissolved in ammonium hydroxide solution and acidified with dilute sulphuric acid may be titrated with permanganate.6 An iodometrie method has also been described.7... 

Determination of Orthophosphates.—(1) With Silver Nitrate.— This depends upon the precipitation of silver orthophosphate in solutions of low and controlled acidity. In the assay of commercial 85 per cent, phosphoric acid of density 1-710 the syrup is diluted to a convenient volume and an aliquot part is taken which contains about 0-1 gram of H3P04. It is neutralised to phenolphthalein with approximately decinormal alkali (free from chloride). 50 c.c. of decinormal silver nitrate are then added while the solution is kept neutral to litmus by stirring in zinc oxide or a suspension of the hydroxide. The whole or a measured part of the filtered solution is acidified with nitric acid and, after the addition of ferric alum, the unused silver nitrate is titrated with standard decinormal ammonium thiocyanate in the usual manner. Alkali phosphates may also be determined in this way. 

There are a number of mineral and metallic salts which have a long association with the alchemical art. The fifteenth century alchemist, Isaac Holland describes The Hand of the Philosophers as being an assembly of important salts in alchemical works. These salts include Niter (potassium nitrate), Sal Ammoniac (ammonium chloride), Vitriol (copper or iron sulfate), Alum (potassium aluminum sulfate), and common salt (sodium chloride).
