Statement I: H₂ from acids cannot be released by Ag

Statement II: Ag is more reactive than H₂

Statement I is correct but Statement II is false

The answer is 3. Statement I is correct, but Statement II is false.

Statement I: H₂ from acids cannot be released by Ag.

This statement suggests that silver (Ag) cannot displace hydrogen gas (H₂) from acids during a chemical reaction. This is correct because silver is not reactive enough to displace hydrogen from most acids. Hydrogen is typically released from acids when a more reactive metal displaces it, a process known as a single displacement reaction. However, silver is less reactive than metals like zinc, aluminum, or iron, which can displace hydrogen from acids. So, Statement I is correct.

Statement II: Ag is more reactive than H₂.

This statement is false. In the reactivity series, hydrogen (H2) is placed above silver (Ag). The reactivity series is a list of metals arranged in order of their reactivity, with the most reactive metals at the top and the least reactive metals at the bottom. Hydrogen, although not a metal, is placed at the top of the reactivity series because it behaves similarly in displacement reactions.

Since hydrogen (H₂) is placed above silver (Ag) in the reactivity series, it means hydrogen is more reactive than silver. Therefore, Statement II is false.

Hence, the correct answer is 3. Statement I is correct, but Statement II is false.
