Module Six is Stoichiometry. My Co-op chemistry class is making precipitates: sodium carbonate and magnesium sulfate, calcium chloride and baking soda, and copper II sulfate and ammonia. Here are notes with the equations for the precipitates, the balanced equation between copper II sulfate and ammonium hydroxide, and the balanced equation between magnesium sulfate and sodium carbonate. HST has copper II sulfate and sodium carbonate. Household ammonia is ammonium hydroxide. Magnesium sulfate is Epsom salts. Driveway Heat is calcium chloride; HST sells these chemicals, too. The Co-op class will be doing Flinn Scientific’s Can You Make 2 Grams? lab. Many of these compounds are hydrates. Here are twelve precipitate reactions with the formulas of the hydrates, products formed, and balanced equations. I will be posting Moore about these lessons and labs.
