Make notes!

In five closed glass bottles five metals are stored: aluminum, gold, sodium, copper and iron plate. While examining their physical properties and their dissolution in acids, the following observations were made:

12

The metal in bottle “A”:

It has a metallic color and it is dissolved both in water and

hydrochloric acid.

13

The metal in bottle “B”:

It is not dissolved in water and concentrated nitric acid, but it is dissolved in hydrochloric acid. The solution obtained after dissolution has a light green color.

14

The metal in bottle “C”:

The metal has a reddish color. It is not dissolved in water and hydrochloric acid, but it is dissolved in concentrated nitric acid while a reddish brown gas is produced.

15

The metal in bottle “D”:

The metal has a low density and a (light) metallic color. It is not dissolved in water and concentrated nitric acid, but it is dissolved in hydrochloric acid. The solution obtained after dissolution is colorless.
