Korleyfah Mouth Chem 331 Thursday 2:00pm Dr. Lijuan Li 20A Preparation of CuCl2~2DMSO 20B Preparation of RuCl2~4DMSO Abstract In order to synthesize our metal complexes‚ we were able to make both Copper and Ruthenium metals. From this‚ we combined each metal complex with DMSO by refluxing the compound. The metal complexes were analyzed through their melting point and IR spectroscopy to determine whether the metal bonded to a Sulfur atom or an Oxygen atom of the DMSO. After analyzing the IR spectrum

In the experiment‚ as the size of the cube decreased‚ the absorption rate increased‚ showing that the smaller cells absorbed more sodium hydroxide than bigger cells. The smaller cells were able to absorb more sodium hydroxide as they have a bigger surface area to volume ratio causing them to act more efficiently than the bigger cells. The smallest cell had a ratio of 1:12 while the biggest cell had a ratio of 1:2‚ leaving a gap of 5:12 causing the bigger cell to act less efficient in absorbing the

Planning AIM Beetroot cells contain a red pigment‚ which is stored in the cell vacuole and a vacuole membrane to prevent this leaking out of the cell surrounds it. The outer of the cell is also surrounded by a membrane‚ which again helps contain the pigment inside the cell. In this experiment I aim to find out the relationship between the leakage of red pigment from a beetroot cell and the surface area. To do this successfully I will need to alter the surface area of the beetroot cells accurately and then
