Question

Which gas isreleased when an active metalreacts with acid ? How will you test for this gas released ?​

Answer 1

Answer:

hydrogen gas is evolved when metal reacts with acid.

When acids react with metals, they produce a salt and hydrogen gas. Most metals react with acids, but not all. The general equation that describes the chemical reaction between an acid and metal is metal + acid = salt + hydrogen gas.

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. you can also observe a pop sound produced due to evolution of hydrogen gas

please mark me brainliest

Answer 2

Zn + 2HCL >>>>>Zncl2 + H2 ^

WHEN zinc reacts with hydrochloride acid it gives zinc chloride and hydrogen gas.

WHEN this is in soap solution it forms bubbles when we place a burning candle near the bubble it creates a pop sounds. Which indicates that the bubble have Hydrogen gas..
