Approximately 100 mL of iodine, a dark blue liquid, was poured into a beaker and about 150 mL of water, a clear liquid, was added to the same beaker, making the liquid about 250 mL in volume. In a flask, 0.11 g of white, powdery vitamin C was measured then 100 mL of water was added to the flask. 20 drops (which is about 1 mL) of starch indicator, a clear liquid, were put in as well. While the buret was at eye level and over the sink, it was rinsed out three times to coat the inside of the glass ...

Handwritten notes and calculation for a chemistry lab on sugar density in a solution

A laptop was set up with LoggerPro and the spectrophotometer was connected. The cuvette was filled with distilled water to calibrate the instrument. The absorbance of the water at 510 nm was indeed found to be 0. Five beakers were set out and labelled with paper towel A, B, C, D, and E. About 0.20 g, 0.41 g, 0.60 g, 0.81 g, and 1.01 g of CoCl2 • 6H2O were measured out and placed in the beaker. The was solid was red. Approximately 25 mL of distilled water were poured into each beaker. The liqui...

Protocol For Solution A: a 100 mL beaker containing about 2.5 g of sugar was used and approximately 48 mL of deionized water was added. The mixture was stirred until all of the sugar was dissolved. The mass of 10.0 mL of the solution was then measured in a 50 mL beaker. The mass was recorded. For Solutions B and C, different amounts of sugar were used and was dissolved into approximately 50mL of deionized water. 10mL of Tang was measured and put into a 100mL beaker and the mass was recorded.
