Investigating the Effectiveness of Acrylic Paint Coatings in Preventing the Corrosion of Zinc, Magnesium, and Iron in Saltwater Environments

This investigation explores the extent to which a single thin layer of acrylic paint prevents the tarnishing of zinc, magnesium, and iron substrates submerged in a 5.99 mol/dm³ saltwater solution.

Using a conductivity probe, the researcher measured the increase in solution conductivity (µS/cm) over 72 hours to quantify ion release. The results demonstrate that the acrylic coating effectively retards corrosion across all metals, with magnesium exhibiting the highest reactivity.

The exemplar is characterized by rigorous data processing, including percentage uncertainty calculations, theoretical % fit analysis, and a comprehensive evaluation of methodological limitations and improvements.
