Abstract

The present process of conducting the laboratory experiments particularly in Chemistry are based on quantitative analysis by conventional techniques are becoming more expensive due to increasing prices of chemicals and apparatus required at large scale, requires minimum six to eight hours for its completion ie time consuming, involves wastage of chemicals and energy, requires concentrated acids at large scalet, requires large volume of ammonia, creates polluted atmosphere in the laboratory. The special efforts are taken in this study to carry out the same experiment by applying microscale techniques. So gravimetric analysis of Fe as a Fe2O3 in presence of Copper was carried out by using microanalysis technique. Ferrous ammonium sulphate with little sulphuric acid was used as a source of Fe and it contains a contamination of CuSO4.Copper is precipitated as a CuS is separated and removed by filtration and the Fe was estimated as a Fe2O3 by precipitation as Fe(OH)3.The study have shown that, there is no conceptual deviation from the results as well as principles of analysis was observed. It has reduced the expenditure on chemicals to a great extent. The apparatus used are of smaller size. This technique requires minimum time, save the energy of a student while performing the experiments, also offers economy of fuel and also minimizes the pollution hazards. The creation of eco-friendly environment in the laboratory was observed which is a need of present world.
