Concentration of a Solution: Beer’s Law The objective of this experiment is to determine the concentration of an unknown copper sulfate solution. You will be using the Colorimeter. In this device‚ red light from the LED light source will pass through the solution and strike a photocell. A higher concentration of the coloured solution absorbs more light (and transmits less) than a solution of lower concentration. The Colorimeter monitors the light received by the photocell as either an absorbance

Asking and Giving Directions This video is talking about Andres Moreno that looked for an ATM and Pazzo’s Pizzeria Restaurant in Colorado. The first people that he met are Adam and Brandon. They said to him to go down the street‚ take a left after the bridge‚ and Pazzo’s Pizzeria would be on his left. Then they said to go down the street then cross the bridge to the right and the ATM would be there. But the directions that they gave were wrong so he asked to another people. The second person

Concentration Camps Can you imagine being a Jew and living during the Holocaust? One day you are at your house doing your normal routine‚ and the next minute you are being loaded onto a cattle truck. You would be taken to the most horrible place imaginable. A concentration camp. A concentration camp was where people were kept without trial. They were kept in terrible conditions and had no rights. Concentration camps had forced labor‚ mistreatment‚ starvation‚ disease‚ and random executions. Concentration

The Experiment Gloria Isham Central Texas College Twenty- six men are chosen to participate in the roles of guards and prisoners in a psychological study led by a Doctor Archaleta for which each participant is to receive $14‚000 after two weeks. Travis has just lost his part time job and is a peace protester who wants to travel to India with his girlfriend. Barris is a 42-year-old who lives alone with a domineering mother‚ who has made him join the experiment to raise money for her hip operation

Experiment to Investigate Osmosis in Potatoes The aim of this experiment is to investigate the movement of water in and out of plant cells. The cells chosen for study will be taken from potato tubers. Firstly I will explain what osmosis is. Osmosis is the passage of water from a region of high water concentration through a semi permeable membrane to a region of low water concentration. This definition contains three important statements: a) It is the passage of water through a semi permeable membrane

Experiment 2: Estimation of protein concentration Introduction Protein assays are designed to measure the total protein in a solution. Protein assays are quantitative if the protein to be assayed is available in sufficient quantity such that one is able to use it to create a standard curve. If this cannot be achieved‚ then a standard protein‚ such as albumin‚ may be used for a standard curve with the understanding that the results on the unknown protein are semi-quantitative. Since most proteins
