Forming a Precipitate
Things are getting a little slippery in an inquiry-based lesson studying precipitates. Learners use soap and Alka-Seltzer tablets to create different mixtures with water. They then study the properties of the mixtures including their...
Beyond Benign
Green"er" Precipitation Reaction
All sodium carbonate may not have the same amount of carbonate, but it should have the same percent. Learners write and balance an equation to predict the chemical reaction between sodium carbonate and zinc acetate. Through the lab...
