Question

which gas is usually liberated when an acid reacts with a metal illustrate with an example how will you test for the presence of this gas?​

Answer 1

Answer:

As acid reacts with metal, hydrogen gas is released. A formation of gas bubbles has been observed along the metal’s surface. The bubbles are then passed into a soap solution, and when a burning candle is held close to the bubble, the gas in the soap bubble burns with a pop sound. As a result, it can be concluded that it is hydrogen since only hydrogen gas produces a popping sound when it burns.

Hydrogen gas is liberated when an acid reacts with a metal. For example, when zinc metal reacts with dil. hydrogen is evolved and salt zinc chloride is formed as: It can be tested by bringing a burning candle near the gas. The candle continues burning with a pop sound.
