Experiment 19 - Determination of the equilibrium constant for the reaction Fe3+ (aq) + SCN( (aq) = FeSCN2+ (aq) Object: To determine the equilibrium constant by a colorimetric method Theory: Colorimetric methods of analysis are usually applied to the determination of small concentrations of either inorganic or organic materials in a solution. The constituent sought must be coloured or must be capable of reacting with a reagent to produce a substance having a suitable colour. Beers Law‚ which

Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater

Communication Needs Communication needs have been identified. One need is the fact that the day shift and night don’t take the time to hand over all the relevant information relating to the work. As a result no communication is in place and the hand over shift don’t have the information required to complete tasks or make the right actions. The other communication need is the communication from the security department to the building staff reminding them of the security policies on site. The
