H₃PO₄(l) + NaI(s) → NR
This is an unbalanced equation; there is no reaction.
Redox reaction balancing is slightly more difficult than conventional reaction balancing but still adheres to a straightforward set of guidelines. One significant distinction is the requirement to understand the half-reactions of the relevant reactants; a half-reaction table is extremely helpful in this regard. Because two half-reactions can be added to create a total net equation, half-reactions are frequently helpful. Although it is necessary to understand the half-reactions in order to complete a redox reaction, it is frequently possible to determine them without using a half-reaction table.
