You Will Need
- Chemistry techniques
- 4 grams purified dihydrate ethylenediaminetetraacetic acid
- 1L volumetric flask
- Powder funnel
- 1L purified water
- Stopper (optional)
Dry and cool
Measure 4 grams of purified dihydrate ethylenediaminetetraacetic acid on the balance and dry at 80 degrees Celsius for one hour before letting it cool to room temperature in the desiccator.
Weigh 3.8 grams and transfer it into a volumetric flask using a powder funnel.
Rinse the funnel by pouring a small amount of distilled or deionized water through it before removing the salt. Then add enough extra purified water to make 700 milliliters. Use a dry, uncontaminated container with a non-glass stopper.
Swirl the solution until all of the powder has dissolved.
Add water and mix
Add more purified water until it reaches the 1-liter mark, and mix well.
Calculate the molarity, or molar concentration, of the solution. The result should be at or very close to 0.01 M.
Store the solution with a stopper. If you plan to use it for titration, it's good practice to conduct the experiment while the solution is still fresh.
