1. Calculations involving molarity Rmr: mole ratios Molarity = number of millimoles of solute/number of milliliters of solution 2. Titration 3. Calculations for acid/base titrations 4. Oxidation/ Reduction Reaction All balanced equations must satisfy two criteria: The same number of atoms of each kind must appear in reactants and products There must be charge balance 5. Balancing Redox Equations 6. Adding ions to balance In acidic solution: we add only H+ or H3O+ In basic solution : we add only OH or H2O

Unformatted text preview: • Acidic solution: • Write half reactions • Balance the amount (number of each) • For each O needed add one H2O • For each H needed add one H+ • Count up charge and add e- to appropriate side • Basic solution: 1. Write half reactions 2. Balance the amount (number of each) 3. For each O needed, add one H2O 4. For each H needed add one H2O to side needing H and one OH- to other side • Calculations for redox titrations...
