Question

Give reasons for inability of non-metals for displacing hydrogen from dilute sulphuric acid.

Answer 1

Bacause of absence of free electrons and high binding energy of non metal

Answer 2

Non-metals doesn't displace hydrogen from dilute sulfuric acid.

Explanation:

• In general, the non-metals are element which are involved in gaining of electrons.
• In the given reaction, the reactants involved are non-metal and dilute sulfuric acid.
• Consider sulfur as the non-metal reacting with the dilute hydrochloric acid.
• Sulfur being electron loving substance doesn't donates electron to react with chlorine atom.
• As this process doesn't occur it doesn't lead to the displacement of hydrogen present in the dilute HCl acid.
• Thus it is inferred that as non-metals are electron loving substance they don't donate or lose an electron and due to this reason, it doesn't displace hydrogen from dilute sulfuric acid.
