Brass analysis
Brass analysis. Image 6 of 7. Performing a titration to determine the percentage of copper in brass. This requires titration of iodine with sodium thiosulphate as the reagent. When the mixture containing the iodine turns pale, starch indicator is added to give a purple colour. When that solution is pale pink the titration is stopped. More starch solution is added and if there is no further colour change then the reaction is over. The stages in this experiment are shown in images A500/566-A500/572

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate process of brass analysis. In image 6 of 7, we witness a meticulous titration being performed to determine the percentage of copper in brass. The key reagent used here is sodium thiosulphate, which reacts with iodine during the titration process. As the experiment progresses, an intriguing sequence unfolds before our eyes. Initially, the mixture containing iodine gradually changes its color from vibrant to pale as it interacts with sodium thiosulphate. To indicate this transformation more vividly, a starch indicator is introduced into the solution, resulting in a mesmerizing purple hue. The precise moment for stopping the titration arrives when the solution turns pale pink. At this stage, additional starch solution is carefully added to ensure no further color change occurs – signifying that the reaction has reached completion. Through these meticulously captured images labeled A500/566-A500/572 by Science Photo Library, we gain insight into various stages of this chemical analysis experiment. The photograph highlights essential elements such as laboratory equipment like burettes and showcases how scientists employ their expertise in inorganic chemistry to analyze and understand complex substances like brass. This print serves as a testament to both scientific precision and artistic beauty found within laboratories worldwide - where researchers tirelessly work towards unraveling nature's mysteries one experiment at a time.
