Pre-Lab Worksheet:
Salt and Water Boiling
- Do you think the boiling point of the solution will increase or decrease as more salt is added? Explain the reason(s) for your hypothesis.
- What is the uncertainty of the Vernier temperature probe?
- What is the uncertainty of the measurement in the liquid volume?
- What is the uncertainty of the measurement of the solid salt?
- Calculate the concentration of a salt water solution that is 50grams of salt in 1000ml of water. Record your answer in (grams of salt)/(ml of water).
- Now calculate the salt mass percent of the solution, again using 50.0grams of salt and 750.0ml of water.
