  2. Skillfully write and interpret thermochemical equations, clearly understanding the relationship between states, stoichiometric coefficients, and energy changes.
  3. Apply Hess’s Law to calculate enthalpy changes for multi-step reactions, and design experiments to measure the heat of neutralization reactions.
  4. Quantitative and microscopic analysis ability: Master calculation of reaction rates and their proportional relationships, and use collision theory to explain the effects of concentration, temperature, and catalysts on reaction rates.
  5. Application of equilibrium principles: Understand the characteristics of chemical equilibrium states, proficiently write equilibrium constant expressions, and predict the direction of equilibrium shifts based on Le Chatelier’s Principle.
  6. Comprehensive control and judgment ability: Master the criteria for determining reaction spontaneity (\Delta G), and apply rate and equilibrium theories to optimize industrial production conditions (e.g., ammonia synthesis).
  7. Understand water ionization and solution acidity/basicity: Master the ion product constant of water K_w, perform simple pH calculations, and comprehend the experimental principles and procedures of neutralization titration.
  8. Master salt hydrolysis rules: Analyze how different salts affect solution acidity/basicity, and apply charge conservation and material balance to handle ion concentration relationships in solutions.
  9. Analyze precipitation-dissolution equilibrium: Understand the meaning of solubility product K_{sp}, and use the relationship between ion concentration quotient Q and K_{sp} to determine whether precipitation forms, dissolves, or transforms.
