the goal:

Understanding the interaction of metals with oxygen

Materials and tools:

A strip of magnesium - Tester filled with oxygen- litmus- A glass of water- holder 

Steps:

Apply the tester filled with oxygen in the middle of the desk

Heat the magnesium bar until It glows 

Then put it in the cylinder filled with oxygen

Now add to the tester an amount of water with shaking and notice what happens

Note:

We notice the increase in the glow of the magnesium strip and its transformation into a white powder

We notice that the powder is dissolved in the water

We notice the blue coloration of the solution

Conclusion:

We can deduct from this the interaction of metals such as magnesium with oxygen, forming metal oxides known as basic oxides.
