Innovating Science Le Chatelier's Principle: A Dynamic Overhead Demonstration

Use an overhead projector to study Le Chatelier's Principle! Fascinating demonstration in which colorless solution is subjected to changes that cause distinct visible reactions Provides students a visual understanding of how the principle can be used to predict the effect of a change in conditions on a chemical equilibrium In this kit, a colorless solution will become dark orange when combined with a solution and a solid. The orange color disappears after the addition of another solid, and reappears upon addition of more solution and more of the original solid. Kit Includes: 1 x 140 ml Potassium Thiocyanate, 0.002M Solution 1 x 10 ml Iron (III) Nitrate, 0.2M Solution 1 x 5 g Potassium Thiocyanate 1 x 5 g Sodium Phosphate, Monobasic, AnhydrousSafety Data SheetDownload HereNGSSPerformance ExpectationsHS-PS1-6Disciplinary Core IdeasPS1.BCross Cutting ConceptsStability and ChangeEngineering PracticesNONEItems NeededNot included in the kit:50mL Graduated cylinder Petri dish2 SpatulasOverhe
