Lesson: Titration Experiments Chemistry • Third Year of Secondary School

Students will be able to

• describe the key steps in performing an acid–base titration,
• describe and understand the experimental equipment used for performing an acid–base titration,
• describe the key steps in preparing standard solutions for acid–base titrations,
• identify suitable indicators by determining the equivalence points in plotted or tabulated pH data,
• identify problems with described titration experiments (e.g., indicator pH range is too high/low/wide, color change is indistinct, and emergence of color is hard to detect so titration must be designed to detect loss of color instead (phenolphthalein)),
• identify hazards encountered during titrations (e.g., splashing of analyte at eye level and tipping of buret).
