Safety

Wear lab gloves and eye protection. Keep a safe distance. Use only dry reagents to prepare the mixture. Don't use large amounts of the mixture because it may be danger.

Always follow general safety recommendations. Please note that conducting chemistry experiments you must comply with the relevant legal procedures in your country.

Reaction formula

Mg + 2 AgNO3 → MgNO3 + 2 Ag

Step-by-step instruction

WARNING! This experiment is dangerous! You should NOT perform this at home. ONLY carry out this experiment, if you are a trained chemist, and you understand local safety and legal requirements, which are required to perform such experiments

  1. Put about 0.5 g of magnesium and silver nitrate mixture onto a nonflammable plate.
  2. Add a drop of warm water using a long pipette. A few seconds later an explosion occurs.

Scientific background

Magnesium displaces silver from its salts, because magnesium is higher in the reactivity series than silver. The reaction between silver nitrate and magnesium is very violent and exothermic.

Due to heat producing, the excess of magnesium burns in air.
