Introduction: The importance of this lab is to get a deeper understanding of how the concepts of solutions and insolubility applies to the lab’s purpose of making chalk using precipitation reactions. A precipitation reaction is when a solid/ precipitate (insoluble) is formed when two solutions that contain soluble salts are combined. Some additional scientific concepts investigated in this lab are insolubility‚ double replacement‚ and limiting reactants. Insolubility occurs when a solute is incapable
