EXPERIMENT NO. 7 Quantitative Analysis of Soda Ash by Double-Indicator Titration ABSTRACT This experiment aims to analyze the percent composition of a substance mixture by using double indicator titration. The analyte used is the soda ash which is titrated with an HCl titrant‚ standardized by 1o Na2CO3. The indicators used are phenolphthalein for basicity and methyl orange for acidity. The two volumes of the titrant are then used to calculate percent composition of soda ash analyte. Statistical

Between pH 2 and pH 9 the percentage of light transmission decreases at a steady rate‚ until it reaches pH 8 where there is a steep increase from 30% to 39% as the enzyme has reached its optimum pH at 8. During the experiment in the boiling tube this pH had the deepest red colour as the most protein gelatine was broken up. This meant that in the colorimeter when testing to see what the light transmission‚ this pH let the least light

would reach a peak level of production and then production would decline as oil became increasingly scarce. How could we tell if oil was becoming scarce and is there evidence that Hubbert was right? This essay will first attempt to identify the indicators of scarcity and then will analyse the debate surrounding Hubbert’s theory of Peak Oil (1956) and whether scarcity is the sole reason for production levels of oil peaking. Introduction M. King Hubbert predicted that oil production in the United
