Redox Titration Lab ABSTRACT: In this lab‚ 0.010 M purple-colored potassium permanganate solution was standardized by redox titration with iron (II) ammonium sulfate hexahydrate (FAS). The average mass of the three flasks of FAS was 0.483 grams. Once the concentration of the standard solution of KMnO4 (aq) was determined‚ it was used to determine the concentration of Fe2+ in iron pills. On average‚ there was 0.01813 L of solution used. With this information and the balanced net-ionic equation

Imagine living in a Puritan society where everyone loves God‚ almost to the point of obsession‚ and will judge a person on anything they think defies his will. The Scarlet Letter by Nathaniel Hawthorne is about a women in a puritan society who committed the crime of adultery and has to wear a scarlet A on her chest to cause public shame. At the end of the book it is revealed that Arthur Dimmesdale was her companion in this affair. Dimmesdale is a very complex character who changes many times throughout

Lung Capacity I. Introduction. The chest contains two lungs‚ one lung on the right side of the chest‚ the other on the left side of the chest. Each lung is made up of sections called lobes. The lungs are soft and protected by the ribcage. The purpose of the lungs is to bring oxygen into the body and to remove carbon dioxide. Oxygen is a gas that provides us with energy‚ while carbon dioxide is a waste product or “exhaust” of the body. | To deliver oxygen to the body‚ air is breathed in through

THEORY When a solid ionic compound is dissolved in water a change of enthalpy is involved. _The enthalpy of a solution_‚ ΔHsol is the enthalpy change when one mole of the substance is dissolved in water to form aqueous solution. � CHEMICAL Sodium Hydroxide (NaOH) PROCEDURE The recommended

Thermochemistry Lab Hypothesis We predict that two different physical changes (dissolving of a chemical substance in water) will produce energy changes; one exothermic and one endothermic. We predict that the temperature change will be affected by the change in system (open vs. closed) will be as follows: the temperature change in the closed system will be greater than that of the open system.

Laboratory #16: Analysis of Grease in Water by Solvent Extraction Experiment Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof
