Utilization of Used-Up Consumer Product Razor Blade for Developing New Experiment
The razor blade has become a commonly available article or consumer product of everyday use. In the present work the double edge stainless steel blades available of some companies in market have been analyzed for their quantitative chemical composition, especially for their important constituents - iron, chromium and to a less extent nickel. Gravimetric method is used for analysis of iron, whereas volumetric method is used for determination of chromium. The spectrophotometric method is tried for estimating nickel. The determination of iron, chromium and nickel from used-up razor blade are newer alternative for usual samples of stainless steel. The work in this study is such that the student of chemistry may get its benefit in learning of experiment developed involving analysis of a common used-up consumer product, razor blade. The student may later think about the relationship between the properties and composition of the material also. This is an attempt for designing an experiment for Analytical Chemistry which may be necessarily incorporated in the practical curriculum for post graduate students of chemistry.
