  • Electrolyte Concentration Lab Report

    DISCUSSION: In this investigation, the effect of electrolyte concentration, depth of electrode immersion in electrolyte, and distance between electrodes in electrolyte, on the current flow through copper electrodes were tested. Table 1 and Graph 1 display the results when increasing electrolyte concentration. Evident in Graph 1, the results contained scatter, and consisted of an outlier in the sample in which the ratio of NaCl: deionised water was 10:30mL. The outlier and scatter may have been due to random errors, which caused the results to be unreliable. Due to this, the raw data does not support the hypothesis. Thus, a line of best fit was drawn in order to reduce the effect of random errors, and statistically remove the outliers, to give a better representation of what the results should have been. This line of best fit suggests that the current flow through the copper electrodes increased as the electrolyte concentration increased, supporting the hypothesis, and corresponding to the research. This would have been because as the electrolyte concentration increased, the amount of Na+ ions and Cl- in the solution…

  • Floating Slimes Essay

    amorphous and typically have compositions of Sb-As-O and Bi-As-O, precipitated in the electrolyte, rather than on the surface of anodes 17. Like the small anode slime particles that are liberated from the anode slimes layer, these floating slimes are generally small and, therefore, are suspended in the solution. They can be transported to the cathode by the fluid flow in an electrorefining cell and get entrapped on the cathode. Some studies on its formation and deposition mechanism and…

  • Acute Kidney Injury: A Case Study

    Introduction During this clinical I had an 85-year-old male, who was admitted with a diagnosis of acute kidney injury. The patient was a very nice individual, which I enjoyed my time with him. He would make a couple of jokes here and there; he would make me laugh. The patient had been there for seven days and was now being discharged. When the nurse told him that he was being discharged he got very excited as he didn’t know that he was finally being discharged. Knowing that he was going to be…

  • Non-Electrolyte Compounds

    If a compound is an electrolyte it conducts electricity by breaking down into ions when dissolved into a solution. A non-electrolyte compound does not dissociate in solution. A non-electrolyte compound cannot conduct electricity because it dissolves in solution as molecules instead of ions. Colligative properties are properties of a solution that depend on the amount of solute dissolved, and not dependent on the identity of the solute. The colligative properties studied in this current…

  • Electrolyte And Redox Reaction Lab

    INVESTIGATE AN ASPECT OF REDOX SYSTEM/REACTION Research Question: Does a higher voltage lead to more mass on graphite? INTRODUCTION Hypothesis: Higher voltage leads to more mass amassed on graphite electrode. Electrolysis- the process in which electric current passes through a solution to effect a chemical change. In this case there is copper, copper sulphate and graphite. In a electrolysis there is an electrolyte which is the copper sulphate, the anode which is the graphite. This is the…

  • Urea And Electrolytes Blood Test Essay

    Urea and Electrolytes Blood Test Your kidneys are a pair of organs designed to maintain the fluid and electrolyte balance of the body. They also perform the important function of removing excess water and soluble wastes from the body to protect it from toxicity. To test the proper functioning of the kidneys, doctors often request for laboratory exams that include a urinalysis as well as urea and electrolytes blood test. Learn more about these tests and how they can help evaluate your kidney…

  • Electrolytic Synthesis Lab Report

    Solutions with a low pH level have a high concentration of hydrogen atoms, they are known as acids. Solutions with a high pH have low concentrations of pH atoms, they are known as bases. Electrolytes can be categorized into two groups: strong electrolytes and weak electrolytes. Strong electrolytes are soluble and completely ionize in water. Weak electrolytes do not completely dissolve and still contain entire compounds and ions in their solutions. Strong acids and bases are typically strong…

  • What Affects The Rate Of Corrosion

    The electrolyte resistivity may be a property of the electrolyte. The definition of an electrolyte is a material that may permit ions to migrate, and also the resistivity of the electrolyte is the rate at which it permits ions to migrate at a given potential. Current is reciprocally proportional to resistivity (V/R=I) and thus, in an electrochemical cell. If the resistivity is doubled, and all different factors stay constant, the quantity of corrosion is cut in 0.5. 3) Contact Resistance The…

  • The Importance Of Ionic Conductivity Analysis

    measurements The complex impedance plots for the polymer electrolytes with different amounts of TBAI /LiI is shown in Fig. 1. It can be displayed that the ionic conductivity increases with the increase in TBAI salt content and reaches the maximum value of 1.737×10-3 S cm-1 at 298 K for 60 % of TBAI content, beyond decreases on further addition of TBAI. At a low content of TBAI, the conductivity is low due to the small number of charge carriers in the electrolytes. However, with an increase in…

  • Schematic Principles Of The Principle Of Electro Chemical Machining

    material from the work piece by electrochemical process. The working principle is anodic dissolution in which the work piece as anode and the tool as cathode. Both electrodes are immersed in the electrolyte and electrical applied to these electrodes. The electric conduction is achieved through the movements of ions between the anode and cathode through the electrolyte. The current is passing through the system of arrangements will cause the dissolution of anode. This process of electrolysis is…
