Redox Reactions Atom 1 Atom 2 Gives electrons This atom Oxidizes itself (loses electrons) It’s the reducing agent This atom Reduces itself (gains electrons)

Balancing Redox Reactions with Oxidation Numbers (see p 462) 1.Assign oxidation number 2.Identify oxidation and reduction 3.Determine the # of e- lost.

Here, we’ll use the half-reactions we came up with and balanced in Part 1 to build an equation for the overall Redox Reaction taking place. We’ll balance.

1/2 reactions AP style. What are 1/2 reactions Reactions in aqueous solutions can be complicated and hard to balance. Our solution… break the one reaction.

Balance Redox Equations: Half Reaction concentrate on electrons, balance each ½ rx. separately Ex: Cr 2 O 7 2- (aq) + Cl - (aq)  Cr 3+ (aq) + Cl 2 (g)

Balancing Redox Equations: Many redox equations can be balanced through trial and error! You have been doing this for a least two years without even knowing.

Pg Balancing Redox Reaction  Can use “old” way: Ag (s) + Fe(NO3)3 (aq)  Fe (s) + AgNO3 (aq)  But what if we have a reaction that looks like.

Half-reactions show the oxidation or reduction reaction separated. Cu (s) + 2 AgNO 3(aq) → Cu(NO 3 ) 2(aq) + 2 Ag (s) Oxidation:Cu → Cu e – Reduction:Ag.

Balancing Redox Reactions Chem 12. Application of oxidation numbers: Oxidation = an increase in oxidation number Reduction = a decrease in oxidation number.

Balancing Redox Reactions. Half Reaction Method 1.Write the formula equation if it is not given. Then write the ionic equation. Formula eq: H 2 S + HNO.

Redox Titrations. Oxidation-reduction reactions involve a transfer of electrons. The oxidising agent accepts electrons and the reducing agent gives electrons.

Oxidation is an increase in oxidation number Reduction is a decrease in oxidation number H 2 + Cl 2 → 2 H Cl Notice: H 2 went from 0 to +1 (

Steps in Balancing Redox 1.Determine the oxidation number of all elements in the compounds 2. Identify which species have undergone oxidation and reduction.
