Determination of Ascorbic Acid in Vitamin C Tablets Done by: lora ID #: Date:12/3/2011 Objectives: The aim of this experiment is to determine the weight of ascorbic acid in three vitamin C tablets by titrating it directly with KBrO3‚ then back titration by Na2S2O3. Introduction: Vitamin C is a weak acid and a water soluble substance and it is often called ascorbic acid. It is useful for many biological activities and main functions such as: it is used to provide reducing equivalents for biochemical

perimeter of circle in c code. This c program makes a contrasting concept that how a return statement can return more than one value. Usually in C programming we make a call by value. This means that in general you cannot alter the actual arguments. But if desired‚ it can always be achieved through a call by reference. Using a call by reference intelligently we can make a function return more than one value at a time‚ which is not possible ordinarily. This is shown in the c program find area and perimeter

The C programming language (often‚ just "C") is a general-purpose‚ procedural‚ imperative computer programming language developed in the early 1970s by Dennis Ritchie for use on the Unix operating system. It has since spread to many other operating systems‚ and is now one of the most widely used programming languages. C also has had a great influence on many other popular languages‚[1] especially [[C++]] which was originally designed as an enhancement to C. It is the most commonly used programming

Research Question: How the amount of vitamin C in fruit juices affects its freshness and till what extent is the information provided on the pack by manufacturers is reliable? Background Information: Hypothesis: -fresh juices have more vitamin C than long-life -juice that is ‘not from concentrate’ is best in terms of vitamin content -if heat destroys vitamin C then heat-treated long-life juices will have lower concentrations -if heat destroys vitamin C then boiled fruit juice will have lower
