halves. Reflux the reaction chamber for 30 minutes over a steam bath. Benzophenone (9.1g) was dissolved in Diethyl Ether (100mL) and added to the reaction chamber and reflux was initiated again for 15 minutes. The reaction was cooled in an ice bath to ambient temperature. A cold acidic solution was created with ice (about 50mL) and Sulfuric Acid (4.5 mL) diluted with water to create the volume of the total solution (~75mL) add this acidic solution to the reaction flask through the condenser…

an unknown solution was identified. After repeated mixing, centrifugation, and decanting, lead was confirmed in Part A and barium in Part B. In Part C, different colored flames of metal species were observed using cation flame tests. Formula unit, total ionic, and net ionic equations were then composed for the identified cations. If the experiment were to be repeated, step 13 could be ommitted as barium was already confirmed in step 12 with the formation of yellow percipitate barium chromate,…

this experiment were to investigate the effect of milk solid content and the varying temperatures of heat pretreatment on yoghurt quality to determine the difference in pH and titratable acidity of fermented milk. In order to carry out this experiment and gain accurate results three variations were tested: yoghurt produced with whole milk pasteurised at 72 °C for 15 seconds, 85 °C for 15 minutes and then whole milk with added 5 % milk solids also heated at 85 °C for 15 minutes, after this…

The discharge of a stream in the total volume of water passing a point along the bank in a second. Most streams are turbulent, meaning that their water swirls in complex patterns. 5. Water meets friction and moves extra slow than at the surface near the middle of the stream. 6. Streams erode the landscape by scouring, lifting, abrading, and dissolving. The resulting sediment provides dissolved loads, suspended loads, and bed loads. The total quantity of sediment carried by a stream is…

granulation. The binder/granulating agent is a semi-solid or solid hydrophilic polymer or a hydrophobic wax. (Michael E. Aulton,…

given two large, black cases that contained a certain number of chemistry kits that gave us directions on how to test everything from the amount of pH in the samples to the amount of ammonia in the riffle, pool, and midstream areas as well as the dissolved O2 levels. Our team started off by splitting into two teams; a group of two and a group of three. The team i was on, the small group of two, worked on testing the phosphate and nitrate in the riffle, pool, and midstream samples. Starting off…

Determining the Percentage Yield of a Chemical Reaction Question: What is the percentage yield of the reaction of sodium carbonate and calcium chloride dihydrate (the dihydrate must be included with the molar mass calculation)? Predictions: Predict the mass of sodium carbonate and calcium chloride dihydrate that will be required to produce 1.90 grams of calcium carbonate: Therefore, the predicted mass of sodium carbonate is 2.0 grams and the predicted mass of…

time. 5. Add 1 mL of concentrated sulfuric acid by allowing the acid to run down the neck of the bottle above the surface of the liquid. 6. Restopper, rinse the top of the bottle to remove any acid and shake well until the precipitate has dissolved. 7. Titrate a volume of treated sample which corresponds to 200 mL of the original sample. This corrects for the loss of some sample during the addition of reagents. This volume calculated using the formula: mL of sample to titrate =…

Like the sodium phosphate buffer, the solid was dissolved in 300 milliliters of distilled in a 500-mL beaker using a stirrer and a magnetic stirring bar. The pH of the solution was then checked using the pH meter and it was brought down to the desired pH of 4.8 using a couple of drops of glacial acetic…

ability of water to pass an electrical current.” This makes sense as to why in the experiment, distilled must be poured on the powders. The source continues to explain that the conductivity of a substance is affected by inorganic solids being dissolved into water. Inorganic solids inside of water have a very low conductivity, so if a powder is tested and it has a very low conductivity, it…
