Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration

Toxicological Chemistry - relates the aspects of toxicology to the chemical structure and reactivity of the toxin. It is concerned with the chemical interaction of the toxin with the receptor that gives the physiological response. The ultimate aim is to relate functional group chemistry of both toxin and receptor to the interaction Toxicity - the degree to which a substance causes damage to an organism Acute toxicity - the adverse effects resulting from a single exposure‚ or exposure over
