Determination of Vitamin C by an Iodometric Titration Purpose: The goal of this lab is to determine the concentration of vitamin C in juices and Real Lemon. A redox titration‚ involving an iodometric method‚ will be used to do the analysis. The samples will be classified by their Vitamin C content. Introduction: Although most mammals can synthesize vitamin C‚ or ascorbic acid (C6H8O6)‚ from sugars‚ man must ingest considerable quantities of this substance. The National Academy of Sciences recommends

been made in the present study to select suitable dilution by using Response surface methodology (RSM) design and to minimize the effects of inhibitory compounds during sulphuric acid (H2SO4) dilution. The treatment of biomass with H2SO4 (1.5%) at 100°C for 30 minutes exhibited optimum results. During enzymatic hydrolysis 16.52 mg/mL glucose was obtained by using 1 mL of enzymatic load at 50oC after 72 hours of hydrolysis. The Glucose thereafter converted to 5.21g/L and 3.69 g/L of ethanol during fermentation

principal at the end of each year. Bond B has a maturity of two years and interest promises an annual rate of 8.85% (4.425% every six months). Compounding occurs semiannually; accrued interest is added to the bond’s principal every six months. Bond C matures in two years and promises an annual interest rate of 8.65% (.0237% per day). Compounding occurs daily; accrued interest is added to the bond’s principal at the end of every day (assume 365 days/year). A. Calculate the annual yield-to-maturity

“C++ Programming Language” An introduction By: De Jesus‚ Antonio L. COMFUN/10:35am-1:35pm /4222/PC#14 January 09‚ 2012 C++ has taken a lot of criticism: it’s a big language that takes a long time to learn; standardization has taken a long time‚ which has made it hard to write portable code; newer languages‚ notably Java‚ draw more media attention. Still‚ among languages that support an object-oriented style‚ C++ is by far the most heavily used‚ and its usage is still growing rapidly. Why

Investigating Vitamin C Background Vitamin C is found in green vegetables‚ fruits‚ and potatoes. It is essential for a healthy diet. The chemical name for vitamin C is ascorbic acid. Ascorbic acid is a good reducing agent and therefore it is easily oxidised. Methods for the detection of vitamin C involve titrating it against a solution of an oxidising agent. Where to start There are several oxidising agents that can be used and a commonly used one is 2‚6-dichlorophenol-indophenol or DCPIP

Hepatitis C is an infectious disease caused by the hepatitis C virus (HCV) that primarily affects the liver. There are different types of hepatitis viruses‚ including hepatitis A‚ B‚ D‚ and E. Among the different viruses‚ hepatitis C is the most serious because it can be chronic and cause severe liver damage. During the initial infection people often have mild or no symptoms. Occasionally a fever‚ dark urine‚ abdominal pain‚ and yellow tinged skin is there. Early on chronic infection typically has

These problems include low self esteem‚ stress‚ depression or anxiety and even in the worst cases‚ suicide.
