    An error that could have been present during the lab includes not letting the zinc react completely with the chloride ions by removing the penny too early from the solution. For instance, the percent error of this lab was 45.6%, which was determined by the subtraction of the theoretical percent of Cu 2.5% and the experimental percent of Cu 3.64% and dividing by the theoretical percent of Cu 2.5%. This experiment showed how reactants react with one another in a solution to drive a chemical reaction and the products that result from the

    While the solution dissolved, 50 mL of distilled water was added to a 150 mL beaker and heated on the hot plate. When the solution started to boil 2.65 grams of Na2SiO3*5H2O was added to the beaker with a stir bar and heated to a gentle boil. When both solutions began to boil, the sodium silicate solution was slowly added to the sodium aluminate. The solution was kept at 900C for 60 minutes and stirred with stir bar. After 60 minutes, the zeolite solution was cooled for 5 minutes and for the magnetized zeolite , 0.78 grams of FeCl3 and 0.39 grams of FeSO4*7H2O was added to the flask and stirred until the iron parts dissolved.

    Consequently, it induces second element to be oxidized. 2. In the experiment #3, zinc electrode acts as anode, where the oxidation processes occur, while iron half-cell acts as cathode, where the reduction processes appear. In the experiment #4, iron is visa verse reducing agent that evicts electrons to copper half-cell through the circuit.

    Introduction: The aim of this experiment was to see whether water, Powerade or orange juice contained more electrolytes. Electrolytes are responsible for controlling the total amount of water in the body, regulating blood volume and maintaining muscle and nerve function. A lack of these electrolytes can cause headaches, fatigue, confusion, hallucinations and muscle spasms. I found that water and distilled water were less conductive than the orange juice and Powerade and orange juice proved to be the most conductive.

    If one compares the amount of electrolytes present in an artificial substance (sports drink), to those in a natural substance (orange juice), then the natural substance will have the most electrolytes. That is my hypothesis. I chose this topic because I have always been skeptical about the validity of the quantity of electrolytes said to be in sports drinks. Sports drinks have been recommended as a way to replace electrolytes, which are lost during exercise. However, orange juice also has electrolytes and these are naturally occurring, not man made.

    Next, a 10 mL beaker is filled with 3 mL of HCl and measure 10 mL of ionized water into a 140 mL beaker. Carefully turn on laboratory burner and start cleaning the Nichrome wire by dipping it into concentrated HCl acid. Hold the Nichrome wire on top of the flame and repeat the step until the wire doesn 't show any color. When the wire is clean, dip the wire again with some of the acid and dip it into the solution with the unknown compound in it. Place the wire back into the flame again and observe the color of the flame.

    When electrolytes, like sodium chloride, dissolve in water, the crystals separate and become ions. Ions are conductors of electricity; the more ions in water, the better it can conduct electricity. For example: salt and tap water have more ions in them than deionized water, which is pure and doesn’t have ions in it, so it won’t conduct electricity as well. Other good conductors of electricity include metals such as copper and aluminum. Objects that don’t conduct are called insulators; these include objects like rubber, glass, and plastic.
