Practical report: Determination of concentration using a standard curve Introduction Spectrophotometer is an instrument that confirms the measurement of specified wavelength of light that passes through medium. The measurement of light absorbance by a solution is also done with spectrophometer. Absorption spectrum Spectrometers are mainly and widely functional in identifying the components of solutions that helps determine the components’ concentrations. Compounds are experimentally identified

are carrying out an investigation to find out how different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads through the house

Practical Task: To compare the concentration of vitamin C in different brands of orange juice. Juice sample provided: 0.1% vitamin C solution‚ fresh orange juice‚ You C 1000 orange water. Aim of investigation: To compare and verify the amount of vitamin C in Mr. Juicy and You C 1000 orange juice. Introduction: Problem: To compare the concentration of vitamin C Hypothesis: Concentration of vitamin C in Mr. Juicy is about 0.02 % Concentration of vitamin C in You C 1000 orange water

EXPERIMENT TO SHOW THE EFFECT OF DIFFERENT CONCENTRATION OF GLUCOSE ON POTATO STRIPS INTRODUCTION: Molecules of liquid and gas are constantly in motion‚ they move randomly in all directions and bounce around in all directions and bounce around and into each other. As they move‚ they tend to spread out moving from areas with many molecules to areas with fewer molecules . This process of spreading out is called Diffusion‚ for example smell of cooking travelling around the house from the kitchen

completely unaware of the horrific events about to unfold that would overshadow their city still today. The citizens of Dachau were oblivious that their city was going to become the origin of concentration camps and of the Holocaust‚ the mass murder committed by the Nazi s in World War II. Dachau Concentration Camp‚ which would soon be placed on the edge of their community‚ would serve as a model for all Nazi extermination camps. This perfect prototype of a Nazi killing machine has come to represent

potatoes and different sucrose concentrations (0.15‚ 0.20‚ 0.25‚ 0.30‚ 0.35 and 0.50). It was expected that the potatoes would lose weight as the potatoes would have lower water potential when placed in a solution ‚ and in this can be taken from the theory of osmosis which states that “the passive diffusion of water molecules across a selectively permeable membrane down a concentration gradient” (Taylor and Bruenn‚ 2009)‚ moving water from a high to a low concentration‚ so in this case water would

Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation

The others take on the cruelest punishment. They’re forced to work in concentration camps where they are split up from their family and children. Children who couldn’t work were forced to death‚ some mothers coming along with their children if they refused to cooperate with giving their kids up. We ask ourselves‚ what made these

Concentration Camps in the Holocaust World War II brought many atrocities‚ 6 million to be precise (Wachsmann 2017). With so many camps not even discovered yet‚ as they are still doing an investigation into all of the locations of the camps‚ but we may not even know how many deaths and the torture of the prisoners by the Fuhrer and the Nazi’s. The Germans had many uses for the concentration camps. A concentration camp is a detention site outside the normal prison system created for military purposes

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
