Working from a word equation depicting a double replacement reaction and the state of both reactants and products, show how to write the total ionic equation after balancing. From the total ionic equation, examine how to write the net ionic equation. Do this for 2-3 textbook problems. In the lab proceed with a mini lab to form a precipitate from magnesium sulfate and sodium hydroxide. Prepare to complete the conclusions and questions after the precipitate settles over night.
