A fresh solution of sodium hydroxide is prepared in a test tube by dissolving 3-4 pellets of it in 5 ml of water. A piece of aluminium foil is dropped into it. A burning match stick is brought near the mouth of the test tube. Then, a pop sound comes. As before, the 'pop' sound indicates the presence of hydrogen gas. Metals react with sodium hydroxide to produce hydrogen gas. So, burning match stick extinguishes.

When we add aluminium foil to freshly prepared sodium hydroxide soluti...
Explanation:
When aluminium foil is added to freshly prepared sodium hydroxide (NaOH) solution, a gas is produced. This gas is hydrogen gas (H2), which is formed through a chemical reaction between the aluminium and the sodium hydroxide.
Here is a detailed explanation of each option and why option 'A' is the correct answer:
a) Colourless and odourless gas which extinguishes a burning match stick:
- Hydrogen gas is indeed colourless and odourless, so this property matches.
- Hydrogen gas is not flammable itself, so it can extinguish a burning match stick when it displaces oxygen from the combustion reaction.
b) Colourless and odourless gas which promotes burning of a candle:
- Hydrogen gas is not known to promote burning, but rather it can be used as a fuel itself.
- It is commonly used in fuel cells and can be burned to produce energy, but it doesn't promote the burning of other substances.
c) Brown coloured pungent smelling gas:
- Hydrogen gas is not brown in colour, but colourless.
- It is also odourless, so it doesn't have a pungent smell.
d) Colourless and odourless gas which produces a pop sound when a burning match stick is brought near it:
- Hydrogen gas is indeed colourless and odourless, so this property matches.
- When a burning match stick is brought near hydrogen gas, it can produce a pop sound due to its high reactivity and ability to combust.
Based on the above explanation, the correct answer is option 'A': Colourless and odourless gas which extinguishes a burning match stick.
When aluminium foil is added to freshly prepared sodium hydroxide (NaOH) solution, a gas is produced. This gas is hydrogen gas (H2), which is formed through a chemical reaction between the aluminium and the sodium hydroxide.
Here is a detailed explanation of each option and why option 'A' is the correct answer:
a) Colourless and odourless gas which extinguishes a burning match stick:
- Hydrogen gas is indeed colourless and odourless, so this property matches.
- Hydrogen gas is not flammable itself, so it can extinguish a burning match stick when it displaces oxygen from the combustion reaction.
b) Colourless and odourless gas which promotes burning of a candle:
- Hydrogen gas is not known to promote burning, but rather it can be used as a fuel itself.
- It is commonly used in fuel cells and can be burned to produce energy, but it doesn't promote the burning of other substances.
c) Brown coloured pungent smelling gas:
- Hydrogen gas is not brown in colour, but colourless.
- It is also odourless, so it doesn't have a pungent smell.
d) Colourless and odourless gas which produces a pop sound when a burning match stick is brought near it:
- Hydrogen gas is indeed colourless and odourless, so this property matches.
- When a burning match stick is brought near hydrogen gas, it can produce a pop sound due to its high reactivity and ability to combust.
Based on the above explanation, the correct answer is option 'A': Colourless and odourless gas which extinguishes a burning match stick.
