Abstract
THE analysis of the lead alloys with antimony and tin has been the subject of much study mainly directed to the development of a satisfactory and rapid method for the solution of the metal. The methods commonly adopted involve the use of hydrochloric acid containing bromine, hot concentrated sulphuric acid, or hot mixed perchloric and phosphoric acids. All give satisfactory results, but all have drawbacks either by reason of the time consumed or by the precautions necessary to prevent the loss of volatile halides and the necessity of varying the composition of the reagent to suit antimony alloys.
