    An investigation into whether the voltage affects the amount of gas produced during the electrolysis of sodium chloride solution. Prediction: I think that hydrogen gas will be produced due to the half equation 2H +2e àH this will be produced at the cathode because opposites attract and the hydrogen ions are positive. At the anode I think that chlorine will be produced due to the half equation 2CL -2e àCL the chlorine ions are negative so they are attracted to the positive electrode. I also think

    the donor. Effective donor sites include thighs, buttocks, and upper arms. Then the donor site is lubricated with sodium chloride and a sterile tongue depressor is placed across the donor site to create a flat surface. The surgeon then applies the dermatome to the donor site and slices off the necessary layer of skin. The newly harvested skin is placed in a sodium chloride solution and is prepared to be meshed. Meshing is advantageous when one wants to increase the ratio of the skin graft. By placing

  • The Effect of the Amount of Sodium Chloride on the Electric Current During Electrolysis

    1979 Words  | 4 Pages

    Sodium Chloride on the Electric Current During Electrolysis Background When an electric current passes through sodium chloride solution, chemical reactions take place at both cathode and anode. If one passes through sodium chloride solution, there will be passage of ions moving through this solution. This results in positively charged sodium ions, which have been dissolved into the solution, moving towards the cathode and deposited there. At the same time, negatively charged chloride ions

  • Dry Cell Battery Essay

    The most common form of a primary cell is the Leclanche cell, invented by a French chemist Georges Leclanche in the 1860s. The electrolyte for this battery consisted of a mixture of ammonium chloride and zinc chloride made into a paste. The negative electrode is zinc, and is the outside shell of the cell, and the positive electrode is a carbon rod that runs through the center of the cell. This rod is surrounded by a mixture of carbon and manganese dioxide

  • Rates of Reaction Experiment

    as you will see in the results, so we have to try and keep it the same throughout the experiment. The reaction we are studying is very easy to monitor and time. All of the products in the solution dissolve into it (sodium chloride, sulphur dioxide and water), apart from sulphur, which makes the solution go cloudy, and forms a precipitate. This can be written down as s-1for example 15.7 s-1means 15.7 per second is the rate of the reaction. The rate is generally measured by selecting a

    similar to the dry cell we use today. The positive pole is a rode of carbon embedded in a black manganese dioxide (MnO2) and Carbon particles and the negative electrode is made of zinc. The electrolyte consists of a mixture of ammonium chloride and zinc chloride made into a paste. This sits in between the negative and positive electrodes, which acts as an ionic conductor. When the cell is in use, atoms of the Zinc in the outer case are oxidized, giving up electrons and forming zinc ions. Zn

    depression: First, the freezing point depression of magnesium chloride was found. To begin, an ice bath was created in a 600 mL beaker filled with ice provided in the laboratory and rock salt. Next, Four different solutions with concentrations of 0.0 g (control), 0.2 g, 0.4 g, and 0.6g of magnesium chloride and 15 mL of deionized water were created. Each solution was made in a 100 mL beaker. The solutions containing magnesium chloride were stirred with a glass rod until the salt was completely dissolved

    lab is to see how the use of diffusion can allow the osmosis to travel across the membrane. To start off there was a sample bag containing sodium Sulfate (NaSO4), and a big beaker of sodium chloride (NaCl). We placed each in testing tubes containing different solutes which were starch, sulfate ion, chloride ion, and protein and saw how they reacted in terms of osmosis (hypertonic, hypotonic,

  • Comparing the Concentrations of Saturated Solutions Experiment

    Concentrations of Saturated Solutions, we set out to find and compare the solubilities of two solids in water. In addition, we tested if solubility is a characteristic property of a solid in a given liquid. This lab allowed us to test and use a reliable way to measure the solubility of a solid. This lab can be replicated for any solid with the same procedure, thus it gives us a method to calculate solubility. The two solids we tested in this experiment were NaCl (Sodium Chloride) and NaNO3 (Sodium Nitrate)

    icy roads can become a large and prominent issue. In 2009 in the United States alone, 477 people were killed in ice-related motor accidents (Icy Road Fatality Statistics, To battle the danger of driving in these conditions, the solution of de-icing the roadways with salt has become a widespread method for preventing accidents. This is because salt is used to melt the ice and snow and keep it from refreezing. The salt works by decreasing the melting or freezing point of the liquid

    1249 Words  | 3 Pages

    DESCRIPTIVE TITLE The Effect of Different Amounts of Sodium Chloride on the displacement of oxygen. INTRODUCTION The dependability of the rate of an enzyme-mediated reaction is based on two factors: the substrate concentration and the concentration and action of the enzyme that catalyzes the reaction (Vander, et. al., 2001). Enzymes are catalysts that produce chemical reactions in cells. Enzymes which are large proteins perform a reaction which acts upon a substance known as a substrate. When

    causes the cell(s) to lose in mass from water diffusing out of the membrane. A hypertonic tonicity is the opposite, where the water concentration inside the cell membrane is lower than the concentration of the solution outside of the membrane, causing the cell(s) to gain in mass and the solution outside of the cell membrane to diffuse water. Isotonic tonicity is when both sides of the cell membrane have the same concentration of water, and diffusion will not occur.
