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).

The concept of a sensitive period‚ that is a phase during development when learning a particular skill can occur more effectively than later on in life‚ is well known in nature. A few examples are imprinting in ducks and song learning for songbirds (Clark 2009). The sensitive period is sometimes

It also is a very important experiment as the use of children for social experiments is not
