unknown solution C ABSTRACT Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119.0C while the boiling point of liquid C was found to

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

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

IB Biology Lab – Vitamin C content of food Aim: To compare the vitamin C content of different fruits using the decolourisation of DCPIP from blue to clear as the indicator. • You first need to estimate the volume of a known concentration of vitamin C solution required to decolourise 2 cm3 of DCPIP solution. • Then you need to determine the volume of fruit juice that decolourises 2 cm3 of DCPIP solution. This gives an estimate of the concentration of vitamin C in fruit juice. • This
