Aim: To calculate the concentration of acid in a sulphuric acid solution. Introduction: A titration is a method of analysis that will allow you to determine the precise endpoint of a reaction and the precise quantity of reactant in the titration flask. A burette is used to deliver the second reactant to the flask and an indicator is used to detect the endpoint of the reaction. So a chemical reaction is set up between a known volume of a solution of unknown concentration and a known volume of

Lab 12: Titration of Acetic Acid in Vinegar Abstract: To lesarn how to titrate chemicals in a lab. Also to be able to determine the concentration of an acetic acid solution. Purpose: To learn how to titrate‚ and calulate the concentration of an acetiuc acid solution. In this case the concentration of vinegar‚ which is diluted acetic acid. Hypothesis: The sodium hydroxide used in this titration would balance out the acetic acid in vinegar. The phenolpthalein‚ a acid –base color indicator

Soluble Vitamins SCI/241 According to the textbook “vitamins are organic compounds that are essential in the diet in small amounts to promote and regulate body processes necessary for growth‚ reproduction‚ and the maintenance of health.” (Grosvenor & Smolin‚ Ch. 7 pg. 200) Vitamins are classified into two groups based of their solubility‚ as some are soluble in water and others are soluble in fat‚ with these characterizations we are able to know more about how the different types of vitamins are

Fat and Water Soluble Vitamins Every day‚ your body produces skin‚ muscle‚ and bone. It churns out rich red blood that carries nutrients and oxygen to remote outposts‚ and it sends nerve signals skipping along thousands of miles of brain and body pathways. It also formulates chemical messengers that shuttle from one organ to another‚ issuing the instructions that help sustain your life. To do all this‚ your body requires raw materials. These include vitamins that your body needs but cannot manufacture

a chelating ligand. The base‚ EDTA‚ will bind to the metal ions‚ which serve as the Lewis acid‚ thus playing a role as a ligand. The indicators used in EDTA titrations are metal ion indicators. Metal ion indicators work by the presence of absence of metal ions. Just like EDTA‚ the metal ion indicators will bind with metals. When the titrations begin‚ Mg2+ will be formed in a complex with the indicator. Once EDTA is added‚ it binds to the free Mg2+ ions‚ and then it reacts with the Mg2+ ions that
