3. What are the total amounts of the salt (g) and of the hydrated salt (g) in the original IV bag?
Salt = _________
Hydrated Salt = __________

1 answer

Sumpin' not right here.

1. What's the metal? What's the EDTA concentration.
2,3,4. Need 1 to answer these.

Did you know?

Did you know that by conducting titrations with EDTA, you can determine the amount of metal ion complexed in a solution? In this example, 4 trials were carried out with a volume of EDTA delivered ranging from 19.50 mL to 20.20 mL. By subtracting the initial volume of EDTA delivered from the final volume, you can calculate the amount of EDTA used in each trial. With this information, you can then determine the amount of metal ion complexed in each titration. Additionally, by knowing the total volume of the IV (50.00 mL) and the volume titrated (5.00 mL), you can calculate the concentration of the metal ion in the IV. Multiplying the concentration by the total volume will give you the total amount of metal ion in the original IV bag in milligrams. Lastly, if you are interested in the total amounts of the salt and the hydrated salt in the original IV bag, further calculations are needed.
