EXPERIMENT 5 Title: Conductivity of Strong Electrolytes Date: 16 August 2005 Objectives: ▪ To determine the relationship between the concentration and conductivity of various electrolytes ▪ To determine the conductivity at infinite dilution ▪ To determine the activity coefficients Theory: The resistance‚ R of a conductor with a similar cross section is proportional to the length (l) and inverse to the cross section area(A)‚ therefore; [pic]

Please choose one electrolyte to research: My electrolyte is: Potassium What is the role of your electrolyte in the human body? To ensure that fluid levels inside and outside the cell are balanced. How does your electrolyte work in the functioning of nerves and muscles? Like athletes when they workout they lose salt by sweating. That’s why they try to contain salt

ions‚ an electrically charged atom. When this reaction occurs it is called an electrolyte at which the solution conducts electricity. The amount of the conductivity value will depend on the ability of the aqueous solution to conduct electricity. Strong electrolytes are solutes that exist either completely or nearly completely as ions‚ which results in a high conductivity value. As it is the opposite of a weak electrolyte were little electricity is conducted. In this laboratory experiment‚ multiple

according to their ability to conduct electricity. Substances whose solutions conduct electricity are called electrolytes and those that do not conduct electricity are called nonelectrolytes. Also electrolytes can be strong or weak. Under strong electrolytes we have NaCl and CaCl2 which are ionic compounds‚ HCI‚ HNO3‚ HBr and H2SO4 are under acids and NaOH‚ KOH‚ and LiOH are under bases. Weak electrolytes are ionic compounds and slightly soluble such as CH3COOH‚ under acids we have HF‚ H2CO3‚ H2SO3‚ and

various ways; it is responsible for transporting oxygen‚ nutrients and waster products. The colorless‚ tasteless liquid is used as a coolant for the body during exercise and vigorous activities which allows it to replace the electrolytes that vanish during work outs. Electrolytes are significant because the heart and muscles rely on them to carry electrical impulses across themselves and other cells. This is very relevant to my everyday life because I have recently started a new workout regiment which

Kidney Failure is a serious medical condition where the kidneys fail to help maintain an electrolyte balance‚ and adequately filter waste products and toxins from the blood (Wordnet). There are many possible causes of kidney failure‚ and unfortunately many unpleasant effects as well. The most common causes for kidney failure are diabetes‚ high

to help his players deal with the heat of the Florida sun. They created a concoction they deemed “Gatorade”‚ named after the team of course. The beverage set out to replenish not only the fluids they lost on the field but the carbohydrates and electrolytes. After they instituted this drink the team began out doing their opponents in the heat and ended the season 7-3‚ But the question here is not “Does gatorade work?” it is “What makes Gatorade work?”
