•
Place container (such as a glass vial or dropper bottle that has a cover)
on an analytical balance.
•
Tare the balance.
•
To make an X NaCl solution weigh out X grams of high purity dried
Sodium Chloride (CAS #: 7647‑14‑5: MW 58.44) directly into the
container.
•
Add distilled or deionized water to the container so the total weight of
the solution is 100 g.
Example with g/100 g NaCl:
g/100 g NaCl g NaCl
g Water
g Total
10 10.000 90.000 100.000
To make a Standard NaCl Solution (g/100 g), follow the procedure on the
