Electrochemistry, Hydrogen, Nitrogen 932 Words 6 Pages Year 11 Lab Report Template Experiment — Modelling A. Hypothesis: Yes, I believe it is possible to determine if this reaction took place by using the oxidation numbers in the equation. Select 10 reactions that produce a precipitate, color change, or gas and write balanced chemical equation and a net ionic equation for each. For example, Silver ions are soluble with Fluoride ions, which would only create an aqueous solution, and the presence of silver ions would not be as evident as they would be if they were paired with Bromide Ions. If the solution appears milky than it is known as a precipitate reaction, meaning it is soluble, and that the ions separated and became surrounded by water. From the initial and final temperature measure, we can tell from the beginning that water's temperature can change very easily, so we can assume from the beginning that water will have the most temperature change when conduct the experiment in the calorimeter. The calculations of a stoichiometry problem depend upon balanced chemical equations.
I then moved to the second row, and place two drops of Sodium Iodine into each of the five nitrate wells. Chemical reaction, Chlorine, Ion 428 Words 2 Pages Round-Trip Copper Reactions Lab The purpose of this lab was to evaluate our skills of decanting a supernatant liquid without losing the solid and successful completion of a series of reactions. Here, you will learn about selecting instruments, chemicals, pouring and decanting. Finally, calculate the theoretical yield using the starting quantities of both reactants and a percent yield based on the recorded weight of your product at the end of the experiment. For example from the lab, Sulfates bonded to Calcium, Barium and Lead are insoluble because they are the exception to the rule.
To determine the species present in aqueous solutions of compounds by using the solubility rules. For each answer, include the address of the website or title and author of a book or article that you used to help you answer the question. Chemical formula, Chemical formulas, Chemistry 1455 Words 4 Pages Fernandez 3. He was born in Berlin, on June 16, 1897, and died August 26, 1987 1. With the product of silver and chloride ions, the presence of the chloride ion will be very evident as it is a solid substance. Cautions from row 1-2 had very few insoluble salts. Also, most of these chemicals are toxic by ingestion.
The following procedure may help you when writing a net reaction for any chemical reaction. Only report the information asked for. To identify which compounds are. Record the requested data below to submit for your lab. For this reason, you are required to thoroughly read through the experiment information presented in the lab manual, and complete a pre- lab for each experiment you do.
I repeated the process for the other test foods as well. For example, water will dissolve with sodium chloride because both sodium chloride and water have a clear positive and negative side. So remember, no food or drinks in the lab! Most cations and anions have an exception that prevents them from being either insoluble or soluble and causes the to be the opposite. Molarity is on the y axis and density is on the x in this case. Report Complete the for your lab report. Yes, I feel like my results were comparable to the rules on the table in the chemistry text. In addition, the written reaction, once balanced, indicates the status of the reaction through the rules of solubility.
These tests were done to give students a better understanding of double replacement reactions. The 'soup' of ions can then react and bond with one another to make a product. Explain what forces must be overcome. If the substance is a good electrical conductor, then it is an ionic compound. Put that molarity into your regression line and calculate the density all other things being equal of this sugar solution.
Boiling, Enzyme, Heat 807 Words 5 Pages. This simplified reaction makes it much easier to identify what occurred during the reaction, by only including what ions reacted to form the products. Ammonia, Chemical reaction, Chemistry 608 Words 3 Pages Chemistry December 14, 2010 Conductivity of Ionic solutions Introduction This lab report is about the conductivity of ionic solutions. I chose 8 because it is a good solid number, it isn't too low or too standard and it isn't too high of a rating. I rate my conclusion an 8 out of 10. Ionic Reactions Introduction: Today we are going to observe the chemical changes when mixing two solutions.
Purpose The purpose of this lab was to observe the results of many double replacement reactions, as well as to practice writing non-ionic, complete ionic, and net ionic equations for precipitation reactions. These changes take precedence over what is found in the lab. Furthermore, some reactions yielded a gas as a product, but it was not detectable by the human eye during observation. A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements. Acid, Aldehyde, Amide 1092 Words 4 Pages living cells that catalyze increase the rate of chemical reactions. The types of information that can be obtained are quantitative and qualitative data.
