The experiment with nitric acid can also be carried out in this way. In the cup we put dry finely chopped straw, heat it as in the first case, and pour 2-3 ml with hot nitric acid. Straw is engaged.

In this regard, glass cylinders with nitric acid must be preserved, observing all safety measures, and in any case not to keep them in baskets with shavings or straw, as other acids retain.

Another interesting experiment with nitric acid can be demonstrated using a chemical beaker, a burner, a ray. Pour some nitric acid into the glass. Let's light the beam, let's get her a little burned. At the tip of the ray formed coal. We lower the glowing coal into nitric acid. There is a bright burning of coal and the release of brown fumes of nitrogen dioxide.

+ 4N3 = 2 + 4N2 + 22.

Carrying this experience with nitric acid, you should follow safety rules, namely work under traction, observe the rules for handling concentrated acids.
