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

88‚ d = 11. (b) a = −29‚ d = 9 (c) a = 58237‚ d = 58168 (actual question is a = 58237‚ d = 58168 ) Solution: (a) Because 88 = 11・8 + 0‚ we have q = 8‚ r = 0. (The fact that r = 0 says that 11|88.) (b) Because −29 = 9・(−4) + 7‚ we have q = −4 and r = 7. (Note that although we can write −29 =9・(−3) + (−2)‚ we cannot use −2 as r because r is not allowed to be negative.)
