The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given

permeable membrane through a process of diffusion. The movement of a solute through this membrane is called dialysis . Diffusion is a form of passive transport. It is the movement of molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors that will affect it’s rate. The rate of diffusion will vary depending on the size of the

Before I came to the concentration camp‚ it was easy to be with your family but I have been in the concentration came for almost 3 months. In the times I been in the camp‚ I met my best friend‚ Graciela. Ever since I been in the concentration camp‚ life has been hard for everyone. In the mornings‚ you are awakened by the kapos in the 4 in the morning where you must raise and find your shoes to work. If someone stole your shoes‚ the person who took them often means they are send to death

Internment Camps vs. Concentration Camps There were two types of camps during WWII‚ internment camps and concentration camps. They each were created in a different place‚ the United States‚ and Europe. They have many differences‚ but also some similarities. Internment camps were created in the United States. They were created for the purpose of containing Japanese-Americans. The United States became fearful after Pearl Harbor got attacked by Japan‚ so they created these camps. The camps were like

Research Paper Concentration Camps The years 1939-1942 marked the expansion of the concentration camps system. The concentration camps took in Jew prisoners for economic profit. The concentration camps also became sites for the mass murder of small targeted groups by the Nazi authorities. The concentration camps were a major role in the Holocaust‚ changing the lives of every Jew‚ leaving a horrible memory for those who did survive the concentration camps. The first concentration camp was camp

The result of mineral content of wheat flour and banana peels is tabulated in table (3) that shows the concentration of phosphorus in wheat flour was the highest (784mg/kg) followed by potassium‚ calcium‚ sodium‚ iron‚ manganese and zinc (427‚ 238‚ 151‚ 38.03‚ 5.72 and 3.19 mg/kg) respectively. In banana peels‚ the concentration of potassium was the highest (16303 mg/kg). The concentration of calcium‚ sodium‚ iron‚ manganese‚ zinc and phosphorus were (3321‚ 440‚ 1217‚ 54.73‚ 1.97 and 641 mg/kg)

Determining the Unknown Concentration of NaHCO3 (aq) Through Titration Introduction Titration is the accurate addition of a titrant- solution in a burette- into a measured volume of a sample (Kessel‚ 2003). There are many different types of titration‚ such as acid-base reaction‚ redox reactions‚ precipitation reaction and more (Dohrman). In this lab an acid base titration will be explored. In an acid-base titration‚ the concentration of an acid or base is unknown and is determined by the adding

“Between 1.1 and 1.5 million people died at Auschwitz; 90 percent of them were Jews” (“Auschwitz”). Concentration camps were large numbers of people; mostly Jews enduring forced labor and mass executions. One of the concentration camps during the Holocaust was Auschwitz. Auschwitz-Birkenau had a unique design‚ a horrible daily life for those in it‚ and is greatly remembered for what happened at these camps at the end of the war. Nazi Germany set up camps with a specific design that would help them

find out the concentration of the sulphuric acid in my experiment. I will do this by titrating the sulphuric acid with sodium carbonate. H2SO4 + Na2CO3 à Na2SO4 + H2O + CO2 Acid + Alkali à Salt + Water + Carbon dioxide Ratio of sulphuric acid to sodium carbonate: H2SO4 : Na2CO3 1 : 1 Concentration of sulphuric acid: H2SO4 is approximately 0.05 - 0.15 moldm-3 The average concentration of the sulphuric acid is: 0.05 + 0.15 = 0.1 moldm-3 2 Concentration (moldm-3) = concentration (g dm-3) Molar
