Drinks (Experiment 23 & 24) Robbie Kinsey Partner: Debnil Chowdhury Chem. 1312-D TA’s: Russell Dondero & Sylvester Mosley Performed Feb. 16‚2000 Purpose The objective of this lab was to determine the concentration of phosphoric acid in cola through two different methods: a pH titration and a spectrophotometer method. Procedure pH titration method First‚ start by preparing a pH meter for use. This was done by using

analysis Date: 29 September 2012 Analysis of Phosphate Introduction The aim of the experiment is to determine the concentration of phosphate ions in unknown samples. A series of dilution of known concentration is performed from the phosphate working solution. Each of the prepared working standards‚ the unknown samples and the blank are then made to react with a mixed reagent which have been prepared after acid wash of the glasswares Glassware * 2 Beakers * 11 conical flasks

2.4 Mechanism Of Phosphate Solubilization: In contrary to Nitrogen soluble Phosphorous is not supplied to plants by atmosphere . Due to this reason the primary and secondary minerals and/or organic compounds are the source of P to great extent. In soil solution concentration of phosphorous is least as compare to other nutrients and ranges from0.001 to 1mg/ml Brady and Weil (2002 ).There are widely three categories of P compounds in soil: (i) compounds which are inorganic‚ (ii) organic compounds

the transmittance to 0%‚ then we changed the mode to absorbance. After we labeled two test tubes which were #5 and #10‚ we inserted water first to set 0 absorbance‚ then we used #5 sample to read it and record absorbance. At this time‚ we set spectronic 20 again for sample #10 by taking sample #5 out and inserted water to set transmittance to 0 then we took the water sample out and inserted #10 sample to read it and record the results. We measured the absorbance of most highly colored tube at wavelength

Water Analysis Lab Report Purpose: In this lab we will be testing a number of water samples. These water samples come from various water sources. Each of these water samples will undergo four different tests. The four tests include a pH test‚ a conductivity test‚ a total and phenolphthalein and alkalinity test‚ and a total hardness test. This lab requires comprehension of lab material and techniques learned in prior labs (Kippenhan‚ 2012). Procedure: Each

Water Wheel Work‚ Power‚ and Efficiency Pre-Lab Preparation: Purpose: The purpose of this lab was to create an efficient water wheel that would produce a productive time in lifting the cup of nuts and bolts that was attached to the pipe used in rotating out water wheel. The more efficient our wheel was the better the time we would have in lifting our cup. We were then able to observe the work that was needed to turn the axel‚ the time that is taken to bring the cup of washers to the axel‚ and

Effects of Phosphate and Nitrate on Pond Water By Claudia Phillips September 6‚ 2014 Block Two INTRODUCTION This lab was designed to study and observe the effects of phosphate and nitrate applied to pond water (1). Phosphorous‚ commonly used in fertilizers‚ is a necessary and vital element for life but can enhance the effects of eutrophication (the over-enrichment of nutrients in water) (2). Nitrate is a common source of food for most algae‚ but too much can make living conditions in
