strumental limitations. For example, if three titrations yield volumes of 24.5 mL, 24.7 mL, and 25.8 mL, the outlier (25.8 mL) demands scrutiny. The lab report discussion should address whether this deviation stems from human error, such as misreading the
against a standardized sodium hydroxide solution using phenolphthalein as an indicator.” Materials and Methods This section demands precision. Lab report answers must enumerate the reagents, apparatus, and procedural steps with clarity. Details such as the volume of titrant added, the
