Acid Determination of Vitamin C Tablets and Salt Solutions Chem 1290-016 03-05-2010 ------------------------------------------------- Purpose: The purpose of this lab was to use acid-base titrations to find the mass percent of ascorbic acid in a Vitamin C tablet. A known concentration of sodium hydroxide was used and the value found was compared to the stated amount of ascorbic acid listed on the vitamin container. Also in this lab the acidity of different salt solutions were tested using

undegraded causing the cells to remain coloured (the oxidized form concentrates intracellularly). The coloured and colourless cells are then counted using a haemocytometer and the number of viable and nonviable cells determined in a given area‚ the result would be then used to estimate the number of cells in the original sample. This is an easy‚ quick and cheap method to determine the amount of viable yeast present in a sample though this is not the best method for a number of reasons. A major reason

Introduction Plants are considered photoautotrophs which means that they draw energy from the sun and use it to form starch molecules. The process by which this happens is called photosynthesis and results in the formation of oxygen and glucose. Plants take in carbon dioxide‚ water‚ and light then release oxygen back into the air. This process happens because of the movement of hydrogen to the hydrocarbons that are produced during photosynthesis. The discovery of photosynthesis is attributed to

In most academic and business studies‚ KMO & Bartlett’s test play an important role for accepting the sample adequacy. While the KMO ranges from 0 to 1‚ the world-over accepted index is over 0.6. In our research‚KMO measure of sampling adequacy is 0.799 which is in acceptable range. Bartlett test of Sphericity comes out to be significant. Values in the table indicate that data collected from the survey are suitable and reliable for further. All testing and reliability

on the reactions (i.e. color changes) of known solutions with indicator solutions. These known solutions contained different types of macromolecules. Each type of micromolecule reacted with at least one indicator solution in a unique way‚ which allowed us to identify the macromolecule based upon the presence or absence of a color change. Water was also used as a control solution‚ as it showed a negative reaction with the indicator solutions. Seven sets of three 10ml test tubes were set up‚ with
