Name two complexes which are used in medicines.

Answer

To answer the question about two complexes used in medicines, we can follow these steps:

### Step 1: Identify the First Complex
The first complex we can name is **Cisplatin**. Its chemical formula is **cis-[Pt(NH3)2Cl2]**.

### Step 2: Explain the Use of Cisplatin
Cisplatin is primarily used in the treatment of **cancer**. It works by interfering with the DNA in cancer cells, preventing them from dividing and growing.

### Step 3: Identify the Second Complex
The second complex we can name is **EDTA**, which stands for **Ethylenediaminetetraacetic acid**.

### Step 4: Explain the Use of EDTA
EDTA is used in the treatment of **lead poisoning**. It works by binding to lead ions in the bloodstream, allowing them to be excreted from the body more easily.

### Final Answer
Thus, the two complexes used in medicines are:
1. **Cisplatin** - used in the treatment of cancer.
2. **EDTA** - used in the treatment of lead poisoning.
