Chemistry Investigatory Project ((new)) -

To find which pH (acidic, neutral, basic) causes fastest rusting.

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

Acidic condition (vinegar) → fastest rusting. To find which pH (acidic, neutral, basic) causes

3 iron nails, 3 beakers, vinegar (pH 3), water (pH 7), baking soda solution (pH 9). To find which pH (acidic
