Lab Report: Scientific Method

Your Name: Alyssa Melincoff

Purpose of this Lab
What is the goal of this lab? What question is it trying to answer, or what problem is it trying to explain?
To find out how table salt affects the boiling temperature of water.

Hypothesis
After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water?
Adding table salt to boiling water will cause the water to boil at a higher temperature

Experimental Design
List the materials used in this lab, and the procedure you followed.

Materials:
1.Kitchen Stove
2. 2 cup measuring cup
3. sharpie
4. measuring spoon set
5.pots
6. digital thermometer
8. table salt
Procedure (list steps in the order in which you performed them):
1. Pour/place 2 cups of tap water into the clean small pot. Heat the pot to boiling. Use the digital thermometer. Record the temperature when the pot reaches a rolling boil.
2. Discard the water down the sink. Allow the pan to cool, then rinse and dry it.
3. Add one tablespoon of table salt to the two-cup measuring cup.
4. Add enough tap water to bring the volume to two cups.
5. Pour this salt solution into the clean small pot. Heat the pot to boiling. Use the digital thermometer. Record the temperature when the pot reaches a rolling boil.
6. Discard the water down the sink. Allow the pan to cool, then rinse and dry it.
7. Add two tablespoons of table salt to the two-cup measuring cup.
8. Add enough tap water to bring the volume to two cups.
9. Pour this salt solution into the clean small pot. Heat the pot to boiling. Use the digital thermometer. Record the temperature when the pot reaches a rolling boil.
10. Discard the water down the sink. Allow the pan to cool, then rinse and dry it.
11. Add three tablespoons of table salt to the two-cup measuring cup.
12. Add enough tap

    Gravimetric Analysis

    • 3 Pages

    Background: Gravimetric analysis is a method which is based on the isolation of the desired sample in pure forms or in some combined form from a sample, and weighing the isolated constituent. Then from the weights of the sample or precipitate, a percentage can be calculated out of the constituent. Solubility is the amount of a substance which is called the solute, dissolves in a volume of liquid substance called the solvent. Sodium chloride can be dissolved in water therefore we can say it is soluble and sand is made up of tiny rock particles or silica which do not dissolve in water therefore insoluble. From the NaCl solubility curve it can be said a slight increase in temperature can assist in dissolving the salt but not by any significant amount.…
