Question

Name any two metals which does not react with sodium hydroxide

Answer 1

Gold and platinum are the metals which do not react with sodium hydroxide.

• Gold and platinum are noble metals. Noble metals are the metals are found in the rawest form in the nature.
• They are resistant to corrosion.
• Noble metals like gold and platinum have a property to avoid oxidation too as they have high oxidization potential.
• Due to high oxidization potential, gold are unable to react with basic and acidic solution to make new products.
• Sodium hydroxide (NaOH) is a basic solution.
• Hence, gold and platinum cannot react with sodium hydroxide.

Answer 2

1. Noble metals are metals found in their purest form in nature.
2. They are corrosion-resistant.
3. Gold and platinum are considered noble metals.
4. They have the ability to avoid oxidation due to their high oxidisation potential.
5. Because of its high oxidation potential, gold cannot react with basic or acidic solutions to form new products.
6. Since, sodium hydroxide$(NaOH)$ is a basic solution, these metals are unable to react with the same.

Hence, gold and platinum are two such metals that are do not react with sodium hydroxide.
