Advanced Chemistry: The Effects
of Acids on Teeth
Leah Chmielewski and Karen Ly
The goal of our experiment
was to find which acid: citric, hydrochloric, or phosphoric acid, created
the greatest percent of mass loss with teeth. Two trials were run,
exposing teeth to each acid, using distilled water as a control.
The teeth were exposed to the acids for about two and a half hours, and
then dried for 21 ours, each day, for three consecutive days. The
results concluded that
hydrochloric acid had the greatest effect
on the teeth. Phosphoric acid had the second greatest effect.
Citric acid had the least amount of effect.
