Experiment 27 oxidation reduction reactions lab report





I cleaned the reaction surface to limit contamination.
The reaction resulted to Na2S4O6 (sodium tetrathionate) and NaI (sodium iodide).
Hypothesis: We believe that the male would have a lower heart rate after running up the stairs determining that he is promo montagne vacances in better shape.
Bromine, Chlorine, Electronegativity 621 Words 3 Pages Open Document Identifying Ionic Compunds Lab Unknown Ionic Compound ILI#3 Abstract: In this laboratory investigation, 8 solutions were combined with each other and an unknown liquid #1 in order to identify the ionic compound in the unknown solution.

Research results are considered qualitative when the results can be answered with a simple statement of yes.
The goal of this experiment is to study the nature of ionic reactions, write balanced equations, and to write net ionic equations.Discussion: In test tube C, the oxidation number of S went up from 2.5, and Is went down from 0 to -1.They occur every day and are vital to some of the basic functions of life.Note that: The chemical which gains electrons is reduced and is called the oxidizing agent.Boiling, Enzyme, Heat 807 Words 5 Pages Open Document Become a StudyMode Member Sign Up - It's Free StudyMode 2019.Which type of compound usually has higher melting points, ionic compounds or covalent compounds?More specifically, the solubility properties of these halogens will be used to predict their reactions.It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly.
