    SODIUM gSodium is a chemical element with the symbol Na (from Latin: natrium) and atomic number 11. It is a soft‚ silver-white‚ highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na. The free metal does not occur in nature‚ but instead must be prepared from its compounds; it was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Sodium is the sixth most abundant element in the Earth’s crust‚ and exists in numerous minerals such

    In this lab‚ I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than

    Investigating the Ratio Between Poly-Vinyl Alcohol and Sodium Borate to form a Bouncing Ball Timothy English Gen. Chem. 1 Lab Section: 009 Introduction: Poly-Vinyl Alcohol (PVA) is a water-soluble synthetic polymer that will be used as one element to form the well know bouncing ball‚ along with Sodium Borate (borax)‚ which has a variety of uses because of its weak base. PVA is ideal for this experiment because it is odorless‚ nontoxic‚ has high tensile strength and flexibility. The

    ­ Chem 102 - Lab #2 Quantitative Analysis of a Soluble Sulfate Steven English Lab Instructor: Dr. Campo Date: Tuesday‚ February 5th 2013 Pre-Lab Questions A. Adding the acid to the sodium sulfate solution results in an increase in the solubility of any free anions present in the sample. This will happen because the present anions will bind with the hydrogen cations present in the acid. B. The sodium sulfate is boiled because experiments have shown that barium sulfate is 50

    • 3 Pages

    Percent Error occurs due to many factors. In this lab by the graph I can state that there was a 100% error in all three unknown substances‚ Pure Leaf Lemon Tea‚ Sprite‚ and Tree Ripe Lemonade. This could be a result of not having properly zeroed the scale or the scale glitching when it came to zeroing it‚ which would have added extra mass and skewed the results. Another factor that could have resulted in a high percent error would have been the scale itself glitching which would have caused the wrong

    “The Synthesis of Zinc Chloride”‚ what a peculiar name for a lab that does not even involve synthesis. Synthesis‚ by definition‚ is when two elements are combined in a chemical reaction‚but that is not the case. In this lab we are combining zinc‚ an element‚ and hydrochloric acid‚ a compound‚ but combining a compound and an element is not synthesis‚ it is single replacement. We are taking zinc and hydrochloric acid and making zinc chloride and hydrogen‚ a single replacement‚ but what occurred during

    Experiment 7: Percentage Composition of Kclo3- A Gas law Experiment Anna CunananProfessor Stewart Chemistry 400 T/TH 1:30 PM 18 March‚ 2014 Objectives: In this Experiment‚ we will be decomposing KClO3 into two different compounds‚ KCl and O2. We are given a known mixture that has MnO2 in it to act as a catalyst. When decomposing KClO3 it releases O2 gas‚ which we then collect into the Erlenmeyer flask. The gas then displaces the water into the beaker‚ which we can then calculate the water evolved

    The moles of sodium thiosulphate can be determined using the average titre values and its concentration. When calculating the average titre values‚ the outliers are ignored because they are mainly created by errors and their great difference from the titres achieved in other trials will pose a great impact to the accuracy of the final result. n=v × c Where ‘n’ is the moles of sodium thiosulphate‚ ‘v’ is the average tire values sodium thiosulphate‚ and ‘c’ is its concentration

    THE CHEMICAL COMPOSITION OF AQUEOUS SOLUTIONS (pp. 94-98) Electrolytes – forms ions when dissolved in water (or certain other solvents) and thus produce solutions that conduct electricity. Strong electrolytes – ionize essentially completely Weak electrolytes – ionize only partially Solution of weak electrolyte will be a poorer conductor than a solution containing an equal concentration of a strong electrolyte Brønsted-Lowry theory Acid is a proton donor Base is a proton acceptor H2O + HNO2 H3O+ +
