Unformatted text preview: call reactions between strong acids and strong
bases NEUTRALIZATION REACTIONS since the
solution is neutral after completion of the reaction
solution Gas Forming Reactions
There are different types of gas forming reactions, but
the most common leads to CO2 formation
All metal carbonates react with acids to form carbonic
acid which decomposes to CO2 and H2O.
acid Redox Reactions
1. If one substance is oxidized, another
If substance in the reaction MUST be
reduced. Reactions are called Redox
2. The reducing agent is oxidized, and the
oxidizing agent is reduced
3. Oxidation is the opposite of reduction.
So, remove oxygen is reduction, to add
oxygen is oxidation
Oxidation-Reduction Oxidation-Reduction Reactions
Oxidation-Reduction Redox and Electron Transfer
Not all reactions involve oxygen, but all
redox reactions involve transfer of eredox
– Substance that accepts e- is reduced
There is a reduction in the charge of an atom When substance loses electrons, positive
charge increase so it will be oxidized
1. Each atom in a pure element has an oxidation # of zero.
Examples: Cu(s), I2, S8
Examples: 2. For monatomic ions, oxidation #=charge of the ion. Mg2+ +2, Na+,
Fluorine always is -1
Cl, Br, I always have oxidation # of -1, except when combined
w/oxygen and fluorine. NaCl -1, ClO- +1
Oxidation # of H is +1 and oxygen is -2 in most compounds.
Except CaH2 H -1, H2O2 O -1
6. Algebraic sum of the oxidation # in a neutral compound must be
Polyatomic ion must equal ion charge Recognizing Redox Reactions
