However‚ for a metal ion indicator to be suitable in n EDTA titration‚ it must not bind as strongly with metal ions as EDTA does. Murexide is therefore suitable. AIM The aim of this experiment is to determine the percentage of nickel in a nickel(II) salt using EDTA. METHOD The following apparatus was collected: 50cmᶟ burette ●Glass stirring rod 20cmᶟ pipette ●Hydrated nickel(II) sulphate (NiSO₄.6H₂O) 100cmᶟ standard flask ●Standardised 0.10moll⁻¹ EDTA solution 250cmᶟ conical flask ●1 moll⁻¹ ammonium

Describe and explain the findings of the vegetation quadrats along a transect on Studland sand dunes. Figure 1 Figure 1 The results of the vegetation quadrats along a transect on Studland sand dunes showed that the amount of vegetation increased and changed‚ while the percentage of bare ground decreased as the sampling sites increased. The reasons behind this can be explained by clarifying what a typical transect is‚ starting with low embryo dunes near the shoreline and much taller mature dunes

Jasmine H Biology lab 100-021 October 4th‚ 2013 Chapter 4- Is It Cereal or Candy? John Harvey Kellogg and his brother Will Kellogg came up with a cereal operation that they called the Sanitas Food Company in the early 1890s. While experimenting around‚ Will made an unsweetened taste of cereal that sold 113‚400 pounds in1896. In doing that‚ he kept the experimenting ongoing with flakes of corn which later would be called the Sanitas Toasted Corn Flakes. Then the sugar was added secretly in. John

AN INVESTIGATION TO FIND THE EFFECT OF BILE SALTS OF ON THE DIGESTION OF LIPIDS I have investigated that if there is an effect of bile salts on the digestion of lipids in the milk. When lipids are broken down in to fatty acids and glycerol (see below)‚ the acid lowers the pH of the mixture. To help me determine and measure the digestion of lipids‚ a pH indicator phenolphthalein has been used to measure the pH of the mixtures. The pH indicator will change the colour from pink to either white (if

Erica Mitchell Mr. Vredenburgh Period 5 52/55 The Effect of Carbon Dioxide on Salt Water Abstract Background: The human population strongly relies on the oceans for food‚ transportation‚ recreation‚ climate regulation‚ and half of the Earth’s oxygen. These oceans‚ that we rely so heavily on‚ are becoming more acidic and less hospitable‚ making ocean acidification the world’s second most important atmospheric carbon problem. This carbon is released into the atmosphere by burning fossil fuels

Aldo Leopold presents many interesting aspects regarding ecology and conservation within his writing of the Land Ethic‚ Round River‚ and “Think like a Mountain”. One statement that stood out among the rest was “Harmony with land is like harmony with a friend; you cannot cherish the right hand and chop off his left". The land is much like the human body—if one part is damaged or sick‚ the effects can be witnessed elsewhere. Like a cancer that attacks the cells‚ the effect of pollution‚ overhunting

The Effect of Salt Concentration on Osmosis in Potato Cells We should first explain what Osmosis is. It’s a passage of water from a region of high water concentration through membrane to a region of low water. Semi membrane is a very thin layer of material‚ which allows some things to pass through them but prevent other things from passing through. The cells allow small molecules like Oxygen‚ water‚ Carbon Dioxide‚ Ammonia. But will not allow larger molecules like Sucrose‚ Starch‚ or protein‚ etc

Today is my fifth clinical assignment here at Salt Lake Regional Medical Center the first of two assignments in same day surgery. I had the opportunity again to work alongside Adriana. I was not sure what to expect‚ I had heard other stories from classmates of the surgeries themselves‚ but not much on what how the nursing process works for the operating room nurse. The role that the nurse has during the surgery is a purely supportive person for the surgeons and both the anesthesiologist and surgical
