- Take four test-tubes and pour water into they.
- Put pieces of metals into each test-tube.
Demonstration of the reactivity of group 2 metals with water
Scientific name: Copmarison of beryllium, magnesium, calcium, strontium and barium in the reaction with water
by David Read
Wear lab gloves and eye protection.
Always follow general safety recommendations. Please note that conducting chemistry experiments you must comply with the relevant legal procedures in your country.
Mg + H2O → MgO + H2
Mg + 2 H2O → Mg(OH)2 + H2
Me + 2 H2O → Me(OH)2 + H2 (Me = Ca, Sr, Ba)
Reactivity of metals increase from berillium to barium. Berillium doesn't react with water, magnesium extreamaly slowly reacts with water at room temperature. Calcium, strontium and barium react vigorously with water.
In thease reactions hydrogen gas and metal hydroxydes are prodused.
