experiment was to determine the percentage purity of the iron(II) salt in an unknown sample. We performed titrations using Potassium permanganate which is a strong oxidizing agent‚ with unknown sample dissolved in deionized water. The result of the experiment was a 99.5% purity for the anhydrous iron (II) ammonium sulfate. Introduction: In this experiment‚ oxidation/reduction (or redox) will be used in the titration analysis of an iron compound. We will use potassium permanganate‚ KMnO4‚ as

In the movie Iron Jawed Angels‚ I viewed the more deeply about the troubles and conflicts that Alice Paul and Lucy Burns had to defeat to complete their most desired goal which was to help women gain Independence‚ and achieve the right to vote in a male based society. All of these hardships that they went through were so significant because it was women like Paul and Burns that helped get the law for women rights to pass‚ women gained so many of the rights and the freedoms that we have today

Section II: Case Study II - The Salt Lake Organising Committee: 2002 Olympics Our analysis of the case study had the following objectives: 1. To focus on the role of the new management in redesigning the organization to ensure successful execution of the 2002 Winter Olympics; 2. To identify the practices involved in the various stages of the project life cycle; 3. To discover how testing and validation reduce risk and uncertainty when planning a one-time event such as the Olympics. The bribery

In Men of Iron by Howard Pyle‚ the theme of fairness is evident throughout the work. The character Myles is too focused on fairness throughout his lifetime. His focus on fairness could have been his downfall many times in the span of his life. First‚ as Myles was sent to Devlen Castle and he began to learn that not everything in life is fair. When Myles first arrives at Devlen he quickly learns that one of his jobs as a squire is to serve the bachelors. He finds this unfair and complains about

percentage by mass of water in Epson salt? DISCUSSION- When a crystal forms from water solutions‚ it takes a certain amount of water as part of the crystalline structures. The water is not covalently bonded to the host molecule or ion. Water is taken up in definite proportion in relation to the mass of the crystalline structure. This water that is trapped inside the hydrated solid structure is called water of crystallization or water of hydration. A salt with associated water of crystallization

The effect of salt concentrations on the mass of the pear cubes ‘Pyrus’ after being soaked in water Aim: The effect of salt concentrations on the mass of the pear ‘Pyrus’ pieces shaped as cubes of 1cm. Background: Osmosis is the net movement of water molecules through a semi-permeable membrane from an area of higher water potential to an area of lower water potential. Water makes up to 70-90% of living cells and cell membranes are partially permeable membranes. Dissolved substances attract

My conclusion is that the higher salt concentration in the solution the greater the decrease in mass of the potato will be‚ the graph I have drawn supports my conclusion. The 10% salt concentration shows that on average the potato loses 2.6% of its overall mass. 20% salt concentration shows a further decrease in mass this time it is an average of 13% overall mass decrease. 30% salt concentration shows an average decrease of 18.8% in overall mass. The 0% salt concentration actually shows a mass increase
