Why Silver Nitrate Needs Special Care

Silver nitrate is highly light-sensitive and can decompose when exposed to light, forming silver metal and other by-products. Over time, light exposure will cause the solution to darken, which reduces its effectiveness.

• Using Amber Dropping Bottles 
  Amber bottles provide an excellent solution for protecting light-sensitive chemicals like silver nitrate. These bottles help block UV light, which is responsible for the degradation of silver nitrate. Select a high-quality amber dropping bottle with a tight-fitting cap to prevent evaporation and contamination
• Wrapping the Bottle with Aluminium Foil
  To further protect your silver nitrate solution from light, you can wrap the amber bottle with aluminium foil. The aluminium foil will create an additional barrier, ensuring that no light reaches the bottle and preventing the silver nitrate from breaking down.

Why Prepare stock of higher molar stock solutions

To save time and improve efficiency as a laboratory technician, preparing stock solutions of higher molar concentration and diluting them to the desired concentrations can be done using a liquid calculator.
