Which of the element’s compounds are used in the treatment of mercury poisoning?a.Copperb.Oxygenc.Sulfurd.Gold

Step 1: Break Down the Problem

We need to identify which of the given elements (copper, oxygen, sulfur, or gold) has compounds that are known to be used in the treatment of mercury poisoning.

Step 2: Relevant Concepts

Compounds used for treating mercury poisoning typically include chelating agents, which are substances that can bind to mercury ions and help to eliminate them from the body. Common chelating agents for mercury include:

• Dimercaprol (also known as British Anti-Lewisite)
• DMSA (Dimercaptosuccinic acid)
• DMPS (Dimercaptopropanesulfonic acid)

Step 3: Analysis and Detail

Now let's analyze each option:

1. Copper - While it has some biological roles, it is not known for any compounds that treat mercury poisoning.
2. Oxygen - Essential for respiration and not related to treating mercury poisoning.
3. Sulfur - Has compounds like DMSA that can act as chelating agents and are effective in the treatment of heavy metal poisoning, including mercury.
4. Gold - Not used in treating mercury poisoning.

Step 4: Verify and Summarize

The only relevant element in this context is sulfur, as it is part of the compound DMSA, which is effective in treating mercury poisoning.

Final Answer

The element whose compounds are used in the treatment of mercury poisoning is c. Sulfur.
