Ethanol is the high-tech fuel used in race cars and dragsters and it comes from corn. I will be doing a deep dive into one of my favorite biofuels or fuel additives where I cover the constraints and benefits in order to get to the truth. Ethanol is basically ethyl alcohol, the same type of...

Abstract The purpose of this experiment was to find out the amount of Copper in a random weight of Copper(II) Sulfate given to us in a volumetric flask. I proceed to carry out the experiment by doing iodometric titration 3 times, using Sodium Thiosulfate as the titrator. 5 color changes were observed during this experiment....

We wanted to test the percent yield when changing Copper into different forms and mixing different compounds with it. When reacting the Magnesium stripes to regain the Copper that had transformed, we expected to get close to 100% yield; which showed that there were minimal errors in the procedure. We reacted to different compounds inside...

Titration Evaluation Today we did a titration in which we had to find the concentration of a solution of hydrochloric acid. Within this experiment we had to use a number of essential scientific skills such as coordination and patience in order for this experiment to be carried out effectively. We had a number of aims...

Titration In the report of titration, finding the unknown concentration we use titration, for example using this method we will find the unknown concentration of the hydrochloric acid using sodium hydroxide to work out the concentration. We need to be very accurate in what and how we do this experiment because if we are not...

Abstract: This experiment seeks to demonstrate the effects of osmosis in potato tissue when exposed to various sodium chloride solutions and how this process can cause weight fluctuations. It is expected that osmosis would occur in an inwards direction when placed in distilled water causing weight gain and in an outwards direction in salt solutions...

Introduction- Cells are the building blocks of every single living thing. Cells have many purposes, they provide structure for the body, yield in nutrients from food and convert the nutrients into energy and finally they are used to perform specific functions. The cell membrane is one of the most important parts of a cell. It...

Introduction ]Each cell, either prokaryotic or eukaryotic, is characterized by some general features like having a cytoplasm, DNA material and a cell membrane. As it was explained by Bhatia and Lal Ichhpujan (2008), the cell membrane, or the plasma membrane, of the bacterial cell is a fragile structure that separates the cell content from the...
