Lab Report: MEASUREMENT OF VITAMIN C Introduction Nutritional diseases were once the number one cause of death only a century ago‚ but rarely affect our lives today. The complete lack of vitamin C (ascorbic acid) characterized by dark purple spots on the skin and rotting gums‚ a disease called scurvy‚ took the lives of many sailors up until the mid 1800s when the prevention was discovered. Consequently‚ British sailors became referred to as ‘limeys’ because of their daily habit of eating

OBJECTIVE To investigate the vitamin C content of different fruit juices. To identify which fruit juices has higher vitamin C content and the lowest vitamin C content. To determine the standard curve of vitamin C based on percentage of vitamin C. To differentiate between fresh juices and carton juices. To consider the reliability and validity of the results. PROBLEM STATEMENT Which type of fruit juices has the most vitamin C content? HYPOTHESIS The smaller the amount of the fruit juices

Identification Strategies In this day and age‚ the amount of communities that have a strong relationship with their local police department is on the decline. The cases that feature corrupt cops all over the media has many believing that all cops function in this same manner. There are several strategies to enlist public help in identification‚ but there are none guaranteed to work for every community. For the most communities‚ despite any possible tensions between the people and the police‚ majority

Table of Contents Model A The very first differential equation that one typically encounters is the equation that models the change of a population as being proportional to the number of individuals in the population. In symbols‚ if P(t) represents the number of individuals in a population at time ‚ then the so called called exponential growth model is: Recall that the general

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

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

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
