Hydrogen reduction
WebReduction reactions involve: 1. Addition of hydrogen: N2 + 3 H2 → 2NH3 ( reduction of nitrogen) 2. Addition of electropositive element: SnCl2 + 2HgCl2 → SnCl4 + Hg2Cl2 ( reduction of mercuric chloride) 3. Removal of oxygen ZnO + C → Zn + CO (reduction of zinc oxide) 4. Removal of electronegative element Web4 okt. 2024 · The reduction potential under acidic conditions is +1.23V, compared to +0.59 V under basic conditions. Tables of reduction potentials are also useful in assessing the opposite reaction. For example, lithium metal spontaneously reduces protons to produce hydrogen gas, becoming lithium ion in turn.
