To determine the molar concentration of acetic acid in commercial vinegar by titration with standardized NaOH.

Commercial vinegar contains approximately 0.83 M acetic acid (about 5% by mass).

Burette, 25 mL pipette, 0.100 M NaOH, phenolphthalein indicator, conical flask, vinegar sample

Pipette 25.0 mL of vinegar into a flask, add indicator, and titrate with NaOH until a faint pink endpoint persists for 30 seconds. Repeat for three concordant titres.

Mean titre 20.6 mL NaOH → 0.082 mol acetic acid per 25 mL = 0.82 M.

The measured 0.82 M is within 1% of the hypothesised value; minor error likely from endpoint judgement. Results support the ~5% labelling.

"To Kill a Mockingbird" by Harper Lee · Southern Gothic / Bildungsroman · 1960 · 281 pages

Set in 1930s Alabama, the story follows Scout Finch as her father, lawyer Atticus Finch, defends a Black man wrongly accused of a crime, exposing the town's prejudice through a child's eyes.

• The protagonist, whose choices drive the central conflict.
• A key supporting character who tests and changes the protagonist.

The novel explores racial injustice, moral growth, and the loss of innocence, arguing that real courage is standing for what is right even when you're sure to lose.

"You never really understand a person until you consider things from his point of view."

A moving, still-relevant read; Scout's narration makes hard themes accessible without softening them.

Rating: 5 / 5
