1. The first part of the second experiment went according to the alternative hypothesis. The 200% saline water moved below the 100% saline water to create a layer. It did not mix with the 100% saline water or tap water. On the other hand, the second part of the second experiment did not support the alternative. Instead of moving above the 100% and 200% saline water and tap water, the 35% saline water remained at the bottom. However, it did try to move up. The reason the 35% saline water did not…

We ran MgCl2 through various tests to see if its properties match our UWC. the first test was to compare the solubility of UWC and MgCl2. We added 1mL of distilled water to two different beakers each and gradually added 1g of MgCl2 and 1g of our UWC to each beaker. Approximately after 15 minutes, both solids dissolved in the water and MgCl2 passed this test. The second experiment was the halide test to determine if there are any Cl- ions in both solutions. We added 1 mL of 6M HNO3 and 1mL of…

CONCLUSIONS: The purpose of this experiment was to find the concentration of the unknown base (NaOH) through a titration. In the experiment, it took 0.95 mL of NaOH with a concentration of 0.53 moles to neutralize 5.0 mL of a 0.100 M of HCl. In the expected result, the concentration of the NaOH was 0.50 moles. The percent error for the lab was only 6%, which means the lab had a fairly high accuracy. Differences between the expected results and the actual result would be caused by the sources of…

1. Synopsis The main aim of the experiment is to find out the percentage of calcium carbonate in toothpaste by using back titration since calcium carbonate is an insoluble salt and does not dissolve in water. Back titration is a reverse method of titration used to obtain unknown concentration of analyte. A roughly weighed quantity of toothpaste? calcium carbonate is dissolved in a known amount of hydrochloric acid and is then titrated against sodium hydroxide. An orange colour will be observed…

using aforementioned equation. Despite the values the pH reading were recorded the values used and reported in this experiment were the calculated pH. Task 2. The standardization of the titrant solution HCL was performed fallowed a potentiometric titration, described in (w), which allowed us calculate the true concentration from four different methods. The sodium bicarbonate with a concentration equal 0.01 mol/L, this value is considered be of high precision and accuracy since…

I sat in the dim lit laboratory waiting for the computer monitor to display the chromatogram of the sample that I had injected into the High Performance Liquid Chromatography (HPLC). I knew the peak chromatogram should come at the thirteenth minute, and if it did, the ophthalmic formulation which had become an axial part of my life over the past many months will have an added chance to become a drug product of the future. Or of course, I might just get a flat line or a confusing mix of…

Assignment 7 Power Station Emission Aim: The aim of this experiment is to measure the mass of sulphur dioxide in 1m3 of flue gas (waste gas from burning fossil fuels in a power station). To achieve this aim, titration of an unknown solution of sulphuric acid (around 0.2-0.4 mol) and sodium carbonate (0.2 mol) using methyl orange as an indicator. 1. Introduction Fossil fuel is formed from decayed plants and animals that have been converted to crude…

amount that was titrated or assumed whole numbers rather than decimal points. We could have also titrated more than necessary considering the color change was not instantaneous. As we performed more titrations we became more diligent with how much we added at a time which could have led to our last titrations being more accurate than our firsts. Another error that was possible was contaminated. We used the same volumetric flask to complete each trial, which meant we had to clean and rinse the…

method of moisture determination is the Karl-Fischer Titration Method (KF). Titration is a technique used to determine the concentration of a known volume of solution. A titrant; that is a solution of known concentration is added slowly in the presence of an indicator until the solution neutralizes. Neutralization is said to occur when the indicator undergoes a color change. ("Titration", 2013) According to S. Nielson the Karl Fischer titration is compatible for foods…

In industry titration is carried out very differently because they use a special machine which reads the results from the end point really rapidly and effectively, they use machines like Kari Fischer automatic titrator which is used to weight the sample, it carries out precise titration and save the data on…
