Chemistry Investigatory Project -

Place one nail in each beaker. Observe and photograph daily for 7 days. Rate rust by visual scale (0 = no rust, 5 = fully rusted).

3 iron nails, 3 beakers, vinegar (pH 3), water (pH 7), baking soda solution (pH 9). chemistry investigatory project

Acidic condition (vinegar) → fastest rusting. Place one nail in each beaker
