Titration for Acetic Acid in Vinegar - Lab Report Example

Proteins that are eluted from gels are used in varied downstream applications successfully, such as protein chemistry, determination of amino acid composition, identification of polypeptides that correspond to specific enzyme activity, and other purposes....

BCG is an acid-base indicator, its acid to base color change is from yellow to blue, with a range in pH from 4.... An alternative to the BCG indicator is Bromcresol Purple(BCP), also an acid–base indicator.... Albumin is chiefly responsible for maintenance of the blood's acid-base balance, commonly referred to as pH3.... 6 This picture shows the bovine albumin amino acid sequence....

At the end point, the pH was neutral as this is the point when there are equal amounts of base and acid in the mixture.... The aim of this lab practical is to carry out the titration of a base, sodium hydroxide with two acids: firstly hydrochloric acid and then sulphuric acid so as to determine the molarities of the two acids. When a base is titrated with an acid, the pH gradually changes until it… At this point there is an equal amount of both the acid and the base....

57 mmol H3O+ The concentration of acetic acid in vinegar therefore: 8.... 1 % acetic acid in vinegarError AnalysisTheoretically, Vinegar contains about 5% (by mass) of a weak acid with a molar mass of 60.... At half-equivalence point, half of the acetic acid has been converted or turned to acetate ion, a conjugate base.... 26 M Molarity = Moles of acetic acid / Volume of Vinegar (in L) =8.... 26 M Mass % = [Mass of acetic acid / Mass of Vinegar] x 100Mass of vinegar = 9....

mmol OH- Because HCL and NaOH react in a 1 to 1 ratio, it means that the number of moles of vinegar that reacted with the base.... mmol OH- Because Unknown and NaOH react in a 1 to 1 ratio, it means that the number of moles of vinegar that reacted with the base.... For instance, in case one has to be using 1M NaOH to titrate HCL and the 1M NaOH has something like a little vinegar because the beaker was not cleaned well during the last lab, molarity will be much smaller since there are impurities in the titrant....

This lab report "The Level of the Key Biomarkers" uses spectrometry enzyme assay and Sandwich ELISA to accurately measure the level of the key biomarkers (i.... .... glucose, insulin and C-peptide) for five samples from unknown patients (A-E).... There was a proportional bias present....

The paper states that the citric acid cycle is a key metabolic pathway that connects carbohydrate, fat, and protein metabolism.... These two acetyl-CoA molecules become oxidized by the citric acid cycle.... Fatty acid oxidation occurs in the matrix when a fatty acid is linked to the thiol group of coenzyme A.... The acetyl CoA is removed from the fatty acid chain during each round and is fed into the citric acid cycle....

When vinegar is mixed with groundwater, it will lose its smell when mixed with contaminated groundwater.... The "Water Quality and Contamination" lab report contains the groundwater contamination experiment in which the author hypothesizes that oil will not mix with contaminate groundwater....
