Data:

Create a data table that will include all the masses and volumes that you have measured in the experiment. Make sure there is a data table for each trial.

Examples: mass of empty beaker, mass of NaCl before experiment, mass of NaCl after experiment, volume of water used, etc.

If you do more than 1 trial, please include the results for each trial. Use 1 table for each trial.

# data[].attributes.body
Procedure:

Your group will need to write their own procedure for the experiment.

Use the lecture on error analysis as a guide.

Include a flow chart that mirrors each step in your procedure

Remember to include all the equipment that you use in your materials list

Materials:

NaCl. Use a mass of about 1-2 grams.

Several pieces of glassware

Heating plate

Electronic balance
Water. Use about 25 mL

Recrystallization of NaCl

CPIPS

Justin Yang, Jackie nguyen, Faye Rodriguez

Pre Lab Discussion:

Recrystallization is one way of isolating an ionic compound from a solution. If several ionic compounds are present in an aqueous solution, then a precipitation reaction may be performed to remove the unwanted ions. In this experiment, a known amount of NaCl will be dissolved in some water, and then recrystallized by boiling off the water.
