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

The book “Night” and its topic of the concentration camps of Auschwitz and Buchenwald is very essential to the story. Wiesel describes these camps with great detail and emotion which got my attention and curiosity. With the research I have collected I learned that Auschwitz and Buchenwald were two major concentration camps to the Nazis in Germany that were mainly for either executing prisoners or forcing them to work in a variety of different fields. These two camps were known more as complexes

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

Introduction Over the course of several weeks‚ myself and my fellow classmates have been researching and conducting an experiment that focuses on the effect of ascorbate peroxidase (a.p) as well as salt stress at different levels of concentrations on Abelmoschus esculentus (okra). Okra is a plant that is composed of 87.1% of water. In addition to being made mostly of water this highly nutritious vegetable is also composed of 0.2% of fat‚ 9.7% of carbohydrate‚ 2.2 % protein‚ 1.0 % fiber‚ and 0

very being caves in and you breathe one’s last. This is how isolation in concentration camps transforms your tranquil soul into a raving madman. Night‚ a memoir by holocaust survivor and professor‚ Elie Wiesel‚ paints the horrors of isolation and how its knives will carve away your flesh and hope until there’s nothing but a vile corpse. In order to avoid the assured effects of this ‘solitary confinement’ in the concentration camps‚ having loved ones were beneficial because they needed one another

Also‚ Jewish Concentration camps were more guarded and higher standardized than the Japanese Internment camps.. Jews were forced to do jobs or they had punishment‚ Japanese weren’t forced to work they could volunteer. Jewish concentration camps and Japanese Internment camps weren’t the same because Jewish camps were more Brutal than Japanese‚ Jews lives weren’t
