An amount of 0.2 mole of AO₃⁻ gains 1.2 mole of electron in a process. Assuming that there is no change in oxidation state of oxygen, determine the oxidation state of 'A' in product.
Options:
Answer:
B
Solution:
Electrons gained per AO₃⁻ = 1.2/0.2 = 6. In AO₃⁻: x + 3(-2) = -1 ⇒ x = +5. After gaining 6 e⁻: +5 - 6 = -1. Hence (b).
