  • Pre-Lab Work Pre-lab work is to be completed on the day the lab is performed. 1. Title The title should be descriptive. For example, “pH Titration Lab” is a descriptive title and “Experiment 5” is not a descriptive title. 2. Date This is the date the student performed the experiment. 3.
  • Experiment 5: In chemistry, pH is a measure of the acidity or basicity of an aqueous solution. Although advanced quantitative pH- considerations often result in fairly acidic calculations, even a basic qualitative pH-assessment requires a good understanding of elemental concepts and ideas.
  • Starting with the third lab period you must do a web-based pre-lab on Loncapa by 7:30am the day your lab is scheduled to start an experiment (see lab schedule). Loncapa will be available after the add deadline and will open by 3pm on Friday, 1/29/16. Starting with the pre lab module for exp. 3 you will be doing post labs.

  • Record the water-bath temperature as detailed in the handout. If you have any questions about operating the calorimeter, please ask before you attempt the experiment. 4. Return your sample cup to room 145 DHE immediately after the experiment. 5. Plot the water-bath temperature as a function of time, and determine the actual temperature rise. 6. 2) Measure half a spoonful of sulfate salt in a beaker. Determine the mass of the salt and the beaker. 3) Pour 5ml BaCl 2 into the beaker. 4) Use a stirring rod to stir the solution. 5) Continue to pour BaCl 2 until it stops reacting with the salt. 6) Take filter paper and measure. Record.

  • Nov 10, 2006 · For your first question, if you can figure out what the total mass of your hydrate is by adding masses of Ca + S + four O+ 4H +two O, you are on your way. Then figure out what percent of that compound is just water. If you take this percentage times your mass of hydrate (10.0 g), you will find what part of that ten grams is just water.
