Potassium manganate

Iron Determination (Using a Standard solution of potassium manganate) During the iron determination experiment, the analytical technique which we used was a titration. We estimated the contents of iron within an iron tablet; we started by dissolving some iron tablets in a solution of sulfuric acid which was weakened. We then proceeded by carrying out a titration in contradiction to a prior standardized potassium manganate(VII) solution. There were both good points as well as bad point for using

HL Year 1). It is the simplest form of carbohydrate. In this experiment, sulphuric acid, H2SO4 and potassium permanganate, KMnO4 is added into glucose with different concentration and the time taken for the purple pink colour of potassium permanganate solution to change to colourless is recorded. This is because glucose donates electrons to the permanganate

Abstract: The experiment was done to demonstrate the effect of ADH on the volume and concentration of urine in order to demonstrate the control of ADH over blood plasma osmolarity. Since non-invasive methods were preferred the volume and concentration of urine was used in place of drawing blood. The results that we our anticipating are that ADH levels in the group of subjects that ingested the 6 gm. Of NaCl would increase over time in response to the increased osmolarity of the blood from all

Part A: Diffusion on a liquid in a liquid. I did an experiment with three different glasses of tap water from the faucet. All three cups measured the same which happened to be 13 cm from the top of the cup to the bottom of the cup. I let the water settle, and sit for about an hour so the temperature was the same for all three cups. I then placed one drop of food coloring into the first glass and waited for the coloring to reach the bottom. I calculated 93 seconds. I then went to the second glass

An investigation into the effects of varying seawater concentrations on two marine invertebrates’ osmoregulatory abilities; Carcinus maenas and Arenicola marina. Introduction The concentration of solutes in the bodily fluids of most marine invertebrates is roughly isosmotic to their environment (Raven, 2008). Because there is no osmotic gradient there is no tendency for the net diffusion of water away from the animal’s cells to occur. When a change in salinity occurs some organisms have the ability

In many ways, any living being is the product of water. The figures are relevant for this assumption: the human body contains 60% water. A newborn has at birth 64% water in his organism while the fetus in the third month of pregnancy has in his tissues, 91% water. As a man ages he starts to dry: around the age of 70, the body contains 46% water. The body is composed of 25% solids and 75% liquid material in which the solvent is water. Furthermore, even the brain tissue is composed of 85% water (Wedro

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane, in a phospholipid bilayer. Phospholipid molecules form two layers, with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid, and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable, and allows oxygen

Assignment 14: Popular, fad, and Weight Loss Diets Taylor Skaggs Roll #735 Oklahoma State University Principle of Human Nutrition 2114 Sec. 007 The DASH Diet 1. Key concepts of the diet: A. What is the DASH diet, and who developed it? The DASH diet stands for Dietary Approaches to Stop Hypertension. The DASH diet was promoted by the United States National heart, lung, and blood institute. The diet was designed to help prevent and control hypertension. In addition to its effect on

Question 1 1.1) What Steps Would You Suggest Should Be Taken To Minimize The Loss Of Vitamins From Food? The steps that should be taken to minimize the loss of vitamins from food is as follows - We should do shopping for foods such as vegetables and fruit from the farm markets or supermarkets that get the fruits and vegetables directly from the farmers. The longer the food stays on the shelves the more it losses the nutrient content therefore obtaining such foods as soon as possible after harvesting

Raghed Odeh Chemistry 227 11/08/2017 Which Alkali Metal Carbonate? Abstract In this experiment, the unknown metal carbonate was put in three different experiments to determine which substance the unknown carbonate had. Gravimetric analysis, simple weight loss and a flame test were done to help determine the unknown metal. The end results supported that the metal was Lithium with a 78.125 g/mol for the first method, a 60.08 g/mol for the second method and a red color for the third method. Introduction
