When metal reacts with acid, there is generally evolution of Hydrogen gas.

Example - Zn + 2HCl ---> ZnCl2 + H2

Test for the gas detection

Bring the gas in a pipe dipped in soap solution. When gas released through the pipe, there will be formation of gas bubbles. Just bring a burning candle near the gas bubbles, if it pops with boom sound, the gas will be H2 or hygrogen.

Answer :

When Metals react with acid Hydrogen Gas and Salt are formed.

Metal + Acid $\implies$ = Hydrogen Gas + Salt

Example - Zn(Zinc) + HCL(HydroChloric Acid) $\implies$ ZnCl2(Zinc Chloride) + H2(Hydrogen)

Test Of Gas :

We can confirm the presence of hydrogen gas by bringing a burning splinter near the test tube. ...If the gas released is indeed hydrogen, then the splinter will extinguish with a pop sound!

Extra Information:

Always member Reaction of Metal With Acids Produce Hydrogen Gas and Salt but reaction of Bases with Acids Produce Salt and Water.

$\implies$ We should never keep lemon pickle or any material which contains acid In Metal Jars. As their reaction Leds the substance emitting foul smell and contaminates the food

$\implies$ The reaction between Metals and Acid depends on reactivity of metal

For Example - Lithium react vigorously with an acid while Platinum doesn't
