Lab 7: Reactions Lab



Purpose: Predicting chemical equations is a fundamental building block of chemistry; balancing equations and identifying states of matter also contribute physical properties to the equations that are especially beneficial in labs. In this lab we completed seven experiments, each with a chemical reaction that created evidence such as: release of a gas, formation of a precipitate, color change, temperature change, emission or absorption of light.


 Favorite Experiment: My favorite experiment was when Hydrogen Peroxide decomposed into water and oxygen with the assistance of the catalyst Manganese Dioxide, which essentially lowers the activation energy needed and creates a new path for the reaction. This reaction was specifically special because the wood splint that we lit and blew out would light itself again in the presence of oxygen.

Lab 18: Alka Seltzer and the Ideal Gas Law

Image
Introduction: Alka Seltzer tablets contain sodium bicarbonate and citric acid, which when dropped in water, dissolve and react to produce carbon dioxide gas. In this lab we dropped 2 Alka Seltzer tablets into a test tube filled with water and then wrapped a balloon around its rim. When the Alka Seltzer stopped fizzing, we measured the circumference that the balloon blew up to. Furthermore, using the ideal gas law, we determined the mass of the carbon dioxide gas produced. after Alka Seltzer was dropped into the test tube Data Table:  Calculations:  Analysis Questions Discuss an area in this lab where experimental error may have occurred.  When we were transferring the ground Alka Seltzer tablets from the plastic tray to the balloon, we inevitably lost some of it and could not remeasure how many grams of the alka seltzer tablet remained. Another source of experimental error was our inability to measure the circumference of the balloon per...

Lab 3: Chromatography

Image
Introduction: This report discusses how, through paper chromatography, we created patterns from a variety of black ink pens on circular pieces of paper. More specifically, this examines how ink passed through a medium, in this case, paper, in which its components move at different rates. The objective of this lab is to understand the process of how a mixture is separated and the physical properties that result from it. Why is it important that only the wick and not the filter paper circle be in contact with the water in the cup? If the entire filter paper were to be in contact with the water, there would be no outward radial spread of the pigments due to the lack of an origin from which water spreads. Therefore, the results that show certain pigments at further distances from the origin would be hindered. What are some of the variables that will affect the pattern of colors produced on the filter paper? The brand of marker used, color of marker used, type o...

Lab 8: Mole Baggie Lab

Image
Summary/Purpose: The concept of using molar mass to identify compounds and convert units from grams to moles, or vice versa, is rather fundamental in chemistry. In this lab we were asked to identify mystery substances by finding their molar masses. For the A2 bag we identified the substance as Potassium Sulfate and for the B1 bag we identified the substance as Sodium Sulfate. A2 Bag:  We were given the mass of the empty plastic bag and how many moles of the compound was in the bag, but had to weigh the bag on a scale to find it's molar mass. The measurements attained were: To find the molar mass we did the following: Out of the given possible compounds, the compound closest to 190 g/mol is Potassium sulfate , which is 174.26 g/mol. B1 Bag:  We were given the weight of the empty plastic bag and the number of molecules in the bag. Additionally, we had to find the weight of the bag with the substance using a scale. The measurements attained were: ...
