Which silver halide is used in medicine

Options

A. `AgNO_(3)`
B. `AgCl`
C. `AgBr`
D. `AgF`

Explanation

To determine which silver halide is used in medicine, we can follow these steps:

### Step 1: Identify the Silver Halides
Silver halides are compounds formed from silver and halogen elements (fluorine, chlorine, bromine, and iodine). The common silver halides include:
- Silver Chloride (AgCl)
- Silver Bromide (AgBr)
- Silver Iodide (AgI)
- Silver Fluoride (AgF)

### Step 2: Research Medical Uses of Silver Halides
Among these silver halides, we need to find out which one has applications in medicine. Silver compounds are known for their antibacterial properties.

### Step 3: Identify the Correct Silver Halide
- **Silver Nitrate (AgNO3)**: Used in various medical applications, but it is not a halide.
- **Silver Chloride (AgCl)**: Known for its antibacterial properties and is used in medicine, particularly in treating wounds and infections.
- **Silver Bromide (AgBr)**: Primarily used in photography, not in medicine.
- **Silver Fluoride (AgF)**: Less common and not widely used in medical applications.

### Step 4: Conclusion
Based on the information gathered, the silver halide that is used in medicine is **Silver Chloride (AgCl)**.

### Final Answer
The silver halide used in medicine is **Silver Chloride (AgCl)**.
