Use caution when using sharp and coarse equipment. Safety Precautions Always wear safety goggles and a lab apron. Determine which ions are spectator ions, then write the net ionic equation for thisreaction.ĬhemLab and MiniLab Worksheets Chemistry: Matter and Change Chapter 9 3 Write the complete ionic equation for this reaction.ģ. Write a balanced chemical equation for the reaction between the NaOH and MgSO4.Most sulfate compounds exist as ions in aqueous solutions.Ģ. Dispose of the solid as instructed by your teacher.ġ. Allow the precipitate to settle, then decant the liquid from the solid into a 100-mLĨ. Slowly pour the Epsom salts solution into the NaOH solution. Mix with another stirring rod until theEpsom salts dissolve.ĥ. Add 50 mL distilled water to the Epsom salts. Measure about 6 g Epsom salts (MgSO4) and place it in another 150-mL beaker. Mix with a stirring rod until each NaOH pellet dissolves before addingthe next pellet.Ĥ. Measure about 4 g NaOH pellets on a balance. Place 50 mL distilled water in a 150-mL beaker.3.
