Gas liberated when dilute acid reacts with a metal:
When a dilute acid reacts with a metal, hydrogen gas is usually liberated. This is because metals react with acids to form metal salts and hydrogen gas.
Reaction with a burning candle:
- When a burning candle is brought near the hydrogen gas liberated from the reaction between the dilute acid and the metal, the hydrogen gas burns with a 'pop' sound.
- This is because hydrogen is a highly flammable gas and easily combustible. When it comes in contact with the flame of the candle, it reacts with oxygen in the air to form water vapor.
- The reaction between hydrogen and oxygen is highly exothermic, releasing a significant amount of heat energy. This rapid release of energy causes the 'pop' sound.
- The flame produced by the burning of hydrogen gas is almost invisible, which is why the 'pop' sound is the most noticeable effect when a burning candle is brought near the gas.
In conclusion, the gas usually liberated when a dilute acid reacts with a metal is hydrogen, and when a burning candle is brought near this gas, it burns with a 'pop' sound due to its highly flammable nature and rapid combustion with oxygen in the air.
