Magnesium salt of EDTA is the same as EDTA-2NaMg?

In summary, the conversation discusses the use of the magnesium salt of EDTA in the standard complexiometric method for determining hardness in water. The speaker questions if the disodium magnesium salt of EDTA is the same as the one mentioned in the procedure. The response clarifies that they are equivalent and that the magnesium salt makes detection of the endpoint easier.

I was reading through the standard complexiometric method of determining hardness in water, and the procedure mentioned the use of the magnesium salt of EDTA. I looked up online to purchase this reagent but all I could find was disodium magnesium salt of EDTA. Are they one and the same? Thanks!

For this purpose they are equivalent.

Not that this particular salt is really required, just EDTA (or disodium salt) can be used as well. Magnesium salt makes detection of the endpoint against the Eriochrome Black T easier.

Beautiful! Thank you for this!
 

1. What is the difference between magnesium salt of EDTA and EDTA-2NaMg?

The main difference between magnesium salt of EDTA and EDTA-2NaMg is the presence of magnesium in the former and the presence of both sodium and magnesium in the latter. Magnesium salt of EDTA only contains one magnesium ion, while EDTA-2NaMg contains two ions - one magnesium and one sodium.

2. Can magnesium salt of EDTA and EDTA-2NaMg be used interchangeably?

Yes, magnesium salt of EDTA and EDTA-2NaMg can be used interchangeably as they both contain EDTA, which is the binding agent. However, the amount of magnesium and sodium in each compound may affect its solubility and therefore its effectiveness in certain applications.

3. Is there a difference in price between magnesium salt of EDTA and EDTA-2NaMg?

Usually, there is no significant difference in price between magnesium salt of EDTA and EDTA-2NaMg. However, the price may vary depending on the manufacturer and the purity of the compounds.

4. What are the uses of magnesium salt of EDTA and EDTA-2NaMg?

Magnesium salt of EDTA and EDTA-2NaMg are both commonly used as chelating agents in various industrial and scientific applications. They can be used to remove metal ions from solutions, as well as to stabilize certain chemicals and prevent them from degrading.

5. Are there any safety concerns when using magnesium salt of EDTA and EDTA-2NaMg?

Both magnesium salt of EDTA and EDTA-2NaMg are generally considered safe to use. However, as with any chemical, it is important to handle them with care and follow proper safety protocols. They should not be ingested and proper protective gear should be worn when handling them in concentrated forms.
