when zinc is dropped into hydrochloric acid whaich gas is formed?
is it zinc chloride?
how would you test for the gas and what would happen?
As for the test. I have seen a person go and place metal in HCl on tv. The way they tested to see whether it was hydrogen gas was to collect the gas in a baloon as the Hydrogen gas was created. Then the sealed the balloon by tying it and subsequently lighted the balloon on fire (while standing very far away). Well, since hydrogen is very flamable, the balloon exploded.
Zinc chloride is a white solid which is soluble in the aqueous solution present in HCl.
When zinc is dropped into hydrochloric acid, the gas that is formed is hydrogen gas (H2), not zinc chloride. Zinc reacts with hydrochloric acid to produce zinc chloride, but also releases hydrogen gas as a byproduct of the reaction.
To test for the presence of hydrogen gas, you can perform a simple test known as the "squeaky pop" test:
1. Collect the gas produced during the reaction by holding an upside-down glass container or test tube over the reaction mixture. Place the opening of the container below the surface of the acid to ensure that the gas is collected.
2. Carefully remove the container and bring a lighted flame or a lit splint near the opening of the container.
3. If the gas is hydrogen, it will react with the flame and produce a distinctive "squeaky pop" sound or a small explosion. This is because hydrogen gas is highly flammable.
It is important to exercise caution and follow proper safety measures while handling flammable gases and performing any experiments.
