Silver chloride (AgCl) is a chemical compound widely used in photography, medicine, and water treatment. This blog post will guide you through essential facts about AgCl, its molecular weight calculation, and practical applications, ensuring you have all the information you need.
What is Silver Chloride (AgCl)?
Silver chloride is an inorganic compound composed of silver (Ag) and chlorine (Cl). It is known for its white crystalline structure and low solubility in water. AgCl is commonly used in:
- Photography: As a component in photographic film.
- Medicine: For its antimicrobial properties.
- Water Treatment: To measure chloride levels in water.
📌 Note: AgCl is highly insoluble in water, making it ideal for specific chemical reactions and applications.
How to Calculate the Molecular Weight of AgCl
The molecular weight of AgCl is determined by summing the atomic weights of its constituent elements: silver (Ag) and chlorine (Cl). Here’s a step-by-step guide:
Find Atomic Weights:
- Silver (Ag): Approximately 107.87 g/mol.
- Chlorine (Cl): Approximately 35.45 g/mol.
- Silver (Ag): Approximately 107.87 g/mol.
Sum the Weights:
Molecular Weight of AgCl = Atomic Weight of Ag + Atomic Weight of Cl
107.87 g/mol + 35.45 g/mol = 143.32 g/mol.
| Element | Atomic Weight (g/mol) |
|---|---|
| Silver (Ag) | 107.87 |
| Chlorine (Cl) | 35.45 |
| AgCl | 143.32 |
