    Marz Jhon V. Patricio QUANTITATIVE DETERMINATION OF THE ACIDITY OF SOFT DRINKS I. Introduction A. Principle Titration is a laboratory method that is the slow addition of one solution to another until the reaction reaches neutralization‚ which is often indicated by color change. Acid-base titration is the most frequently used procedure to determine the concentration of an acid or basic solution. This titration is also called as neutralization reaction. By adding an indicator to the solution‚ we will

    beer). We would be comparing the concentration of ethanol to that of 25%propanol which would act as an internal standard. Method To set up the standards for a calibration curve we would make solutions of different concentrations of ethanol. Using a 25cm3 volumetric flask we would put 10cm3 of 25% Propanol into each one which would act as an internal standard. We would then add differing amounts of ethanol (0.5 cm3‚ 1.0cm3‚ 2.0cm3and 4.0cm3) and then top the volumetric flask up with distilled

    for the biogasoline analysis. Biogasoline catalytic cracking process requires detailed qualitative and quantitative analysis of the hydrocarbon composition of its oil and fraction. In this analysis‚ their fractional composition‚ saturated vapor pressure‚ density and antiknock rating will be investigated. By knowing the qualitative and quantitative composition of the gasolines‚ the content of n-paraffin‚ isoparaffin‚ aromatic‚ naphthene‚ and olefin (PIANO) groups of hydrocarbons as well as of oxyorganic

    Physics. I will perform these experiments using three different measuring tools (graduated cylinder‚ burette & pipette) to evaluate the precision of each one. Results: Density 1‚ 2 & 3 calculated by using graduated cylinder to obtain volume. Density 4‚ 5 & 6 calculated by using volumetric pipette to obtain volume. Density 7‚ 8 & 9 calculated by using burette to obtain volume. All experimental values obtained have been included in this determination. Average density calculated numerically:

    constituent elements. The purpose of this lab was to test for law of definite proportion through determining percentage composition of each element in Magnesium oxide. I hypothesized that the composition mass of magnesium will be more than oxygen and this would be the result for other groups as well. My null hypothesis was that if the experiment is done accurately‚ the percentage composition of magnesium shouldn’t exceed 65%. Material: -Refer to lab manual on page 180 in Nelson Chemistry 11. -The following
