1.0 Title Determination of Protein Content Using Kjedahl and Titration 2.0 Introduction Proteins are polymers. They are the source of dietary amino acids and are used for growth and maintenance of living systems. They are costlier sources of energy compared to carbohydrates and fats and hence the human body utilizes proteins mainly for biosynthesis rather than as an energy source‚ though the energy yield is 5 kcal/g of protein. Twenty different types of amino acids occur naturally in proteins

repeated. Coa(C2O4)b.cH2O + heat ( Co3O4 A 300 ml 0.5 M sulfuric acid solution was created by adding 25 ml of 6 M sulfuric acid to 275 ml of distilled water. A buret was then cleaned and filled with the KmnO4 solution. Next‚ 10 to 15 ml of 0.1 M sodium oxalate solution was added to 100 ml sulfuric acid and placed in an Erlenmeyer flask for titration. The solution was then heated to around 60 degrees Celsius. The solution was then titrated until a faint pink/purple color remains for about thirty

Synthesis of Salicylic Acid and Potentiometric Determination of its Purity and Dissociation Constant ------------------------------------------------- Abstract The purpose of the study is to synthesize salicylic acid from the ester‚ methyl salicylate‚ and determine the acid’s dissociation constant and purity. The ester was converted to salicylic acid by base hydrolysis. The products were refluxed and recrystallized‚ to ensure maximum purity‚ and filtered‚ dried‚ and weighed. The melting point

the base NaOH. The equation for the titration reaction is as follows: H3C6H5O7 + 3NaOH -----> 3H2O + Na3C6H5O7 But before proceeding to the titration of soft drink samples‚ the exact concentration of NaOH must be known through the process of standardization which involves performing a titration with a known amount of a stable acid‚ which in this case is the monoprotic acid potassium hydrogen phthalate.

2. Regarding the diabetes example in this unit 3: Consider how you would use HIT for standardization. What groups would you consider for segmentation? Why? There are three types of diabetes. I think the best way to get a controlled study on them all is to Bundle. Bundling is a group of situations that are related to a disease process that‚ when executed together‚ result in better outcomes than when implemented individually. We first must group each category accordingly Type
