Experiment 18 Chemistry 101 Redox Titration: Determination of the Percentage of Iron in a Sample INTRODUCTION The concentrations of redox-active species can be determined by redox titrations. In a redox titration‚ a measured sample of the unknown is titrated against a standard solution of a substance that will oxidize or reduce the unknown. In the present experiment you will take a sample containing iron‚ add acid to dissolve it [thereby converting all the iron to iron(II)]‚ then

Batch Reactor Aim/Objective The aim of this experiment is to compare the theoretical conversion for a saponification reaction to the experimentally determined conversion in a batch reactor under constant temperature conditions. Experimental Procedure The first step was to ensure the electrical supply to the rig was turned off and that the Armfield batch reactor was empty and clean. 500mL of 0.1M sodium hydroxide solution was then added manually. The pump and stirrer were then set to

Total continuity equation is the principle of the conservation of mass when applied to a dynamic system. The unit of this equation is mass per time. In overall balance‚ only one TCE can be written. CCE is based on component balance. Unlike mass‚ chemical components are not conserved. If reactions occur on a system‚ the number of moles of an individual component will increase if it is a product and will decrease if it is a reactant. The unit of CCE is moles of component per unit time. While EE‚ the

Question 1 Issues Arising From Case The issues are the future viability of the plant for producing EPC and the long-term effects of not upgrading this production line. The additional upgrade will result in additional production‚ but as mentioned by the sales director if there is no demand for the increase in supply and Rotterdam plants excess will be added to the Mersey side quantities the plant upgrade could ultimately result in a dropping of prices to shift supply. The transport division is also

Abstract Philosophy has not paid sufficient attention to engineering. Nevertheless‚ engineering should not use this as an excuse to ignore philosophy. The argument here is that philosophy is important to engineering for at least three reasons. First‚ philosophy is necessary so that engineers may understand and defend themselves against philosophical criticisms. In fact‚ there is a tradition of engineering philosophy that is largely overlooked‚ even by engineers. Second‚ philosophy‚ especially ethics

different members of a team Football teams There are many different roles in the modern football team; teams consist of 11 players with one player in the goal and the rest playing outfield all the roles of the different members of the team are vital in the team winning a game. Goalkeeper The goalkeeper is a very specialised role compared to all the other members of a team‚ a goalkeeper will rarely end up playing in a different position‚ where as other members of the team e.g. midfielder may
