The misadvertised brand
Home Brand vinegar was advertised as having the same
amount of vinegar (acetic acid) as all the major brands. One of the
major brands took legal action, stating that the amount of acetic acid
is twice as much in their brand as it is in Home Brand.
Tests were conducted to verify the claims.
The burettes were calibrated before the tests started. A known sample of vinegar was titrated with a known concentration of sodium hydroxide(base). Look at the diagram on the right and calculate the amount of base added.
