6) When balancing oxidation–reduction reactions in acidic solution by the half-reaction method the addition of H2O is required to balance the
Select one:
a. O2
b. OH–
c. O
d. H2O
e. none of these
Your answer is c. O
In acidic medium we add one H2O molecule for balancing single oxygen. As number of hydrogens increases by adding water molecule then we add H+ .

In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the half-reaction method or the oxidation number method. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In either method H2O(l), OH?(aq), and H+(aq) may be added to complete the mass balance. Which...
Part IV: Balancing Redox Reactions in Acidic and Basic Solution General rules for balancing redox reactions in acidic or basic solution: 1. Divide the redox reaction into two half-reactions. One that contains the element that gets Oxidized and one that contains the element that gets reduced. 2. Focusing on one half-reaction at a time, balance all non-H and non-0 atoms. 3. Balance the O atoms by adding water molecules to the side with too few oxygens 4. Balance the H...
In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the half-reaction method or the oxidation number method. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In either method H2O(l), OH−(aq), and H+(aq) may be added to complete the mass balance. Which...

Balance the "breathalyze" test reaction in acidic solution, as in example 18.2 on tro C_2H_5OH + Cr_2O_7^2- rightarrow CH_3CO_@H + Cr^3+ Balance in basic solution as in example 18.3 on p Fe(OH)_3 + SnO_2^2+ rightarrow Fe + SnO_3^2-
Course Home <Chapter 20 Homework Balancing Redox Equations: Half-reaction Method Review Constants Periodic Table In addition to mass balance, exidation reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the hall reaction method or the oxidation number method. The hall reaction method balances the electrons lost in the odation all reaction with the electrons gained in the...
