- 1.4: Synthesis of Aspirin (Experiment)
- Analgesics are compounds used to reduce pain, antipyretics are compounds used to reduce fever. One popular drug that does both is aspirin.
- 1.5: Determination of Kc for a Complex Ion Formation (Experiment)
- The objectives of this experiment are to find the value of the equilibrium constant for formation of FeSCN2+ by using the visible light absorption of the complex ion and to confirm the stoichiometry of the reaction.
- 1.6: Equilibrium and Le Chatelier's Principle (Experiment)
- A reversible reaction is a reaction in which both the conversion of reactants to products (forward reaction) and the re-conversion of products to reactants (backward reaction) occur simultaneously. A reversible reaction at equilibrium can be disturbed if a stress is applied to it and the reversible reaction will undergo a shift in order to re-establish its equilibrium. This is known as Le Chatelier’s Principle.
- 1.7: Group I cations
- Selective precipitation of group I cations comprising of lead(II), mercury(I), and silver(I) is based on the general solubility rule that states "salts of chloride, bromide, and Iodide are soluble, except when the cation is lead(II), mercury(I), or silver(I)." Separation of group I cations and their identification based on selective dissolution and characteristics of the ions are described.
- 1.8: pH Measurement and Its Applications (not the one we did)
- The objectives of this experiment are to measure the pH of various solutions using pH indicators and meter, to determine the value of Ka for an unknown acid, to perform a pH titration (OPTIONAL, if time permits), and to create and study the properties of buffer solutions.
- 1.16: Synthesis and Recrystallization of Aspirin
- Analgesics are compounds used to reduce pain, antipyretics are compounds used to reduce fever. One popular drug that does both is aspirin.
