Chemistry - Acids and Bases - Bronsted-Lowry theory - Proton Pass!
Word-catch game themed around proton transfer. The screen shows H⁺ (protons) falling. Catch them with 'BASE' buckets (proton acceptors) and avoid catching them with 'ACID' buckets (proton donors). Bases to catch with: NH₃, OH⁻, H₂O (when acting as base), CH₃COO⁻. Acids that donate (don't catch): HCl
