1. If you were the president of the Win Metal Company‚ what decision would you make regarding this controversy? Explain why. 1. Single supplier Solutions for lack of sulphuric acid: -‘’Sulphric acid is a material used in the production of viscose fibres‚ so in addition to the environmental effect‚ the recovery of sulphric acid will entail considerable savings. WSA plants can eliminate hydrogen sulphide and carbon disulphide contained in the off-gases by converting these sulphur compounds

tests required by the EPA. The experiment will be performed by a four person group‚ with each person providing a different water sample. The four tests to be performed are: pH‚ conductivity‚ phenolphthalein and total alkalinity‚ and total and non-carbonate hardness. Data from these four tests will be gathered and analyzed‚ drawing conclusions “about the validity of the data as well as the quality of water” (Kippenhan 137). All of the techniques that will be used in this lab have already been learned

Food Analysis * Concerned with development of criteria of quality and identity… * Process in w/c sample is treated in a series of steps Importance: 1. It’s necessary in the dev’t and enforcement in standard of identity‚ purity and feel of processed food products. 2. It can provide studies design to improve and control the quality of natural processed food. 3. Can help in the determination of the composition of products in their normal and abnormal storage conditions. Methods
