10. MAKING A STANDARD SODIUM CHLORIDE SOLUTION
To make a Standard NaCl Solution follow the procedure below:
y
Place container (such as a glass vial or dropper bottle that has
a cover) on an analytical balance.
y
Tare the balance.
y
To make an X NaCl solution weigh out X grams of high purity dried
Sodium Chloride (CAS #: 7647-14-5) directly into the container.
y
Add distilled or deionized water to the container so the total
weight of the solution is 100 g.
Example with g/100 g NaCl:
