Redox Net Ionics Oxidation number on at least two elements must change.
Types of Redox RXNS • RXNs: • Single replacement, synthesis, and some decomposition. • To predict products look at the reactants to see if there are oxidizing and reducing agents. • When a problem mention acidic or basic solution, most likely a redoxrxn • When balancing, remember to add H+ and HOH
Example • A solution of tin II chloride is added to an acidic solution of potassium permanganate. • 5Sn⁺² + 16H⁺ +2MnO₄⁻ Mn⁺² + 5Sn⁺⁴ + 8HOH
