• Salt Dissolve Water Dissolved Temperature
    506 words
    I Introduction A. Purpose: The purpose of this experiment was to determine if the temperature of water effects the rate at which salt dissolves. B. Hypothesis: If the temperature of the water increases then the rate at which the salt dissolves will increase. C. Science Concepts: Solution- one substance dissolved in another Solute- the substance that gets dissolved Solvent- the substance that the solute gets dissolved in Characteristic property- a property that is unique to a substance, does not...

    Faster Dissolved Oxygen Test Kit Purpose The purpose of my project is to determine if there is any significant difference in dissolved oxygen (DO) levels as measured by the traditional HACH (R) method or the newly developed CHEMets (R) test kit under typical field conditions. Hypothesis My hypothesis is that there is no significant difference in dissolved oxygen (DO) levels as measured by the traditional HACH (R) method or the newly developed CHEMets (R) test kit under typical field conditions. ...
  • World War I French Revolution

    World War I was definitely a greater contributor to the course if European civilization than the French revolution. WWI dissolved empires and shaped a generation of men, Where as the French Revolution primarily affected France and didn't even abolish the monarchy. WWI brought things like the Treaty of Versailles in 1919, this dissolved Germany as a power, but also brought forth mass retaliation in the form of Nazi movement. Because of this Czechoslovakia emerges as independent. WWI also started ...
  • Water Quality Carbon Dioxide
    842 words
    Water quality is a complex term to evaluate. The health of a water ecosystem depends on so many things. These parameters are each intertwined and connected. For simplicity there are several mainstream parameters that are used in conjunction with each other to determine the water s quality. These include: alkalinity, ammonia content, carbon dioxide, chlorine, nitrates, dissolved oxygen, phosphates, temperature, and turbidity. The most visible sign of poor water quality remains to be animal popul...
  • Phosphates And Dissolved Oxygen
    829 words
    Phosphates are present in many natural waters, such as lakes and streams. Phosphates are essential to aquatic plant growth, but too much phosphate can lead to the growth of algae and results in an algae bloom. Too much algae can cause a decrease in the amount in dissolved oxygen in the water. Oxygen in water is affected in many different ways by phosphates Phosphorus is usually present in natural waters as phosphate (Mc welsh and Raintree, 1998). Phosphates are present in fertilizers and laundry...

    SCIENCE REPORT AMMONIUM NITRATE NH 4 NO 3 Problem Our task was to investigate what the optimum ratio of solute to solvent that will produce the maximum cooling / heating effect? Hypothesis With a smaller quantity of water (50 mls) and the same amount of Ammonium Nitrate added. After any period of time the mixture will be a cooler temperature than that of a mixture with a larger quantity of water. Variables"X Water"X Teaspoons"X Time"X Ammonium Nitrate"X Thermometer"X Stirring (used thermometer) ...
  • Dissolved Oxygen Water Levels Gas
    629 words
    Research Dissolved oxygen infers to the volume of oxygen that is contained in water. Oxygen enters water through photosynthesis and across the water interface. The amount of oxygen that can be held by the water depends on the water pressure, salinity, and temperature. Gas solubility increases with decreasing temperature; thus colder water holds more oxygen. A reason why freshwater holds more oxygen than does saltwater is because gas solubility increases with decreasing salinity. When there is a ...
  • Sludge Test Boiling Point

    DAY 1 The first day there wasn't much time to do anything, but I filtered the yellow stuff out of the mixture. I am pretty sure that it was sulfur. It didn't have much of an odor, but the mixture itself smelled like rubbing alcohol, isopropanol. DAY 2 On this day, I did fractional distillation of the liquid (s). The graph is on the attached sheet. From doing the distillation I noticed two plateaus. The first plateau was at 80 C, and the second was at 100 C. I wasn't positive on this day what th...
