about determining the quantitative amount of sulphate inside barium sulphate‚ BaSO₄‚ using the method of gravimetric analysis. This quantitative determination is done by the addition of a dilute solution of barium chloride slowly to a hot unknown sulfate solution slightly acidified by concentrated hydrochloric acid‚ HCl. The white precipitate of barium sulphate is filtered off‚ washed with water‚ oven-dried‚ and weighed as barium sulphate. The quantitative amount of sulphate is deduced from mathematical

Case Studies Abstract Alfredo Cano Abstract Innovative methods in language teaching may sometimes be slightly difficult for less experienced teachers. Case studies are a relatively new type of task-based activities for business English students. They have been used in language courses for some time now. It seems‚ however‚ that their full teaching potential has not been used yet. Teachers seem to be uncertain of how to use cases in class.The paper presents the main pedagogical aspects of

Copper Sulphate Calibration Aim The objective of this experiment is to determine the unknown concentrations of solutions. Introduction With the use of absorption of light a spectrophotometer sends UV wavelengths through solutions to determine their concentrations. The light absorbed is measured as the atoms‚ molecules and ions absorb the wavelengths of light that the spectrophotometer gives off (Meah‚2013). The level of light transmitted defines the amount of light absorbed‚ for instance‚ the lower

Quantitative Analysis: % Copper in an Ore May 3‚ 2006 Abstract: In this experiment we were given an unknown sample of ore. Using the spectrophotometric analysis and the electrogravimetric analysis‚ we found the unknown percentage of copper in the unknown sample of ore was to be 17.6% by mass. Introduction: Chemical analysis takes place under two different scenarios. In one case‚ you need to find out the chemical identity of some material. The first kind of analysis‚ in which the chemical
