Abstract: The purpose of this experiment was to determine the concentration of an unknown amount of copper sulfate using the spectronic 20. Four solutions of different concentrations of H₂O and CuSO₄ were put into the spectronic 20 to observe their absorption of light. Then‚ a graph was created to plot down the measurements. Using the calibration curve of the graph‚ the concentration of the unknown substance was found out to be .12M. Background/Introduction: Beer’s law (which states that

POLLUTION!!- IS THERE A SOLUTION? Human Beings belong to a species that poisons its own habitat. If we think of our planet as a spaceship then we are the new and all other species are passengers. In general we behave irresponsibly .Earth’s atmosphere forms a protective cocoon around our spaceship‚ storing and recycling essential elements such as carbon and oxygen. Humans fill the air with pollution that turns the rain acidic and threatens to alter the climate pollution from and fossil and nuclear

investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar‚ the solute‚ will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions are divided

sack -saturated NaCl w/food coloring -beaker with distilled H2O The experiments begins with the construction of a simple osmometer by obtaining pre-soaked length of tubing ‚opened and tied at the end. The tube is filled with saturated NaCl solution (with added food coloring) and the thistle is inserted in the dialysis tubing. The dialysis tubing is sealed to the thistle funnel with dental floss and placed in a beaker filled with distilled H2O until it is fully submerged. At 6:18 p.m. the

Based on calculations #7 made above for solving the molecular weight‚ it was identified that the unknown liquid was Butanoic acid: 88.1g/mol. Since the calculated value was 83.5 g/mol‚ it was assumed that Butanoic acid was the only solute out of all that were listed that shared a similar value. In reference to the results and data used for calculation the molecular weight (MW) for the unknown was successfully proven to match the accepted value of 88.1 g/mol. More specifically‚ this was evident due

The Phyco-Solution Algae are emerging to be one of the most promising long-term‚ sustainable sources of biomass and oils for fuel‚ food‚ feed‚ and other co-products. What makes them so attractive are the large number and wide variety of benefits associated with how and where they grow. Nearly all these benefits stem from the fact that these plants have evolved over billions of years to produce and store energy in the form of oil‚ and they do this more efficiently than any other known natural or
