Part 2: Equipment Setup and Initial Measurements
This section details the proper setup of titration apparatus and initial solution measurements. The arrangement of equipment is crucial for accurate results.
Vocabulary: Titrant - The solution of known concentration added from the burette Vocabulary: Analyte - The solution of unknown concentration being analyzed
The setup includes proper positioning of the burette, stand, and clamp, along with preparation of both sodium hydrogen sulfate and sodium hydroxide solutions.

Part 3: Titration Procedure and Data Collection
The detailed titration procedure explains the step-by-step process of determining the unknown concentration.
Highlight: Multiple titrations are performed to ensure accuracy, with the first serving as a rough estimate.
Definition: The endpoint is reached when a permanent color change occurs, indicating complete neutralization.
The process includes careful measurement of 25.0cm³ of sodium hydroxide solution and systematic addition of sodium hydrogen sulfate while monitoring color changes.

Part 4: Calculations and Safety Considerations
This section focuses on the mathematical aspects of determining concentration and important safety protocols.
Highlight: When calculating the mean volume, the first rough titration and any outlying results are excluded.
Example: Titrations must be within 0.1cm³ of each other to be considered valid for calculations.
The risk assessment portion emphasizes the hazardous nature of the chemicals used:
Quote: "Corrosive to eyes - can cause serious eye damage"

Part 5: Final Calculations and Analysis
The concluding section guides students through the final calculations to determine the unknown concentration of sodium hydroxide.
Definition: The concentration calculation uses the balanced equation and the precise volumes measured during titration.
Highlight: Accuracy in recording and calculating results is crucial for reliable concentration determination.
The practical emphasizes the importance of showing all working steps in calculations and maintaining precise measurement records.

Part 1: Introduction and Solution Preparation
This section outlines the fundamental setup for preparing an accurate volumetric solution for titration analysis. The reaction between sodium hydrogen sulfate and sodium hydroxide is explained, along with the role of phenolphthalein indicator.
Definition: A volumetric solution is a precisely concentrated solution used for quantitative chemical analysis.
Example: The reaction equation demonstrates the process: NaHSO4 + NaOH -> Na2SO4 + H2O
Highlight: Phenolphthalein serves as the indicator, changing from pink/purple to colorless at the endpoint.
The equipment list includes essential items such as a volumetric flask, weighing boat, digital balance, and various measuring tools needed for precise solution preparation.
