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

tamin C‚ ascorbic acid‚ is one of the most important vitamins found in citrus juices‚ including orange juice. Often projects find that orange juices made from frozen concentrated orange juice (FCOJ) have the highest vitamin C levels as compared to freshly squeezed or not-from-concentrate (NFC) juices. This is probably due to the fact that vitamin C degrades over time in fresh and NFC‚ but doesn’t degrade as much in FCOJ due to it being frozen until reconstitution. If one is comparing a NFC product

“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

Topics in C Programming Bob Hain Introduction This document is not intended to be a text on C programming. Because many of you may not have had the opportunity to use or practice C programming‚ we are attempting to provide a brief description of some of the elements of C which you will need in your laboratory work. We will leave out many topics but will try to provide simple‚ although sometimes incomplete‚ explanations of some of the basic elements of C. Why C? The computer industry is changing

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

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
