Question

which element is extracted in presence of copper by adding EDTA​

Answer 1

Answer:

The element that is extracted in the presence of copper by adding EDTA is Iron.

Explanation:

• Iron can be extracted from its compounds by using a complexing agent such as EDTA (ethylenediaminetetraacetic acid).
• EDTA can chelate or form a complex with iron ions, making them more soluble and easier to extract.
• The presence of copper in the solution can complicate the extraction process as copper ions can also form complexes with EDTA. However, copper is less likely to form a stable complex with EDTA compared to iron.
• By carefully controlling the conditions, iron can be selectively extracted in the presence of copper by using EDTA.
• This extraction process is commonly used in analytical chemistry for the determination of iron in a sample.

Answer 2

Answer:

Iron is the element that is extracted when EDTA is added when copper is present.

Using a complexing agent like EDTA, iron can be separated from its compounds (ethylenediaminetetraacetic acid).

Iron ions can be chelated or complexed by EDTA, which makes them more soluble and easier to remove.

Copper ions can also form complexes with EDTA, which might make the extraction process more difficult when copper is present in the solution. However, compared to iron, copper is less likely to form a stable combination with EDTA.

Iron can be selectively removed in the presence of copper by employing EDTA under precisely controlled circumstances.

In analytical chemistry, this extraction technique is frequently used to determine the presence of iron in a material.
