By: Juno Kim and Nicole Introduction The goal of this experiment was to determine the mass percent of manganese in an unknown steel sample using methods of visible spectroscopy and volumetric analysis. The two methods were then analyzed and compared to decide the better method for determining the composition of Mn in the unknown steel. In both methods, the unknown steel was digested in hot concentrated Nitric acid, HNO3, and analyzed for transition metals. An accurate analysis of steel […]
