CHEMLAB 10 ACTIVITIES OF METALS SERIES

By comparing how different metals react with the same ions in aqueous solutions, an activity series for the tested metals can be developed. 2 Chemistry: Matter and Change Chapter 9 ChemLab and MiniLab Worksheetsħ CHEMLAB 9 Develop an Activity Series Some metals are more reactive than others. Determine which ions are spectator ions, then write the net ionic equation for this reaction. Write the complete ionic equation for this reaction. Most sulfate compounds exist as ions in aqueous solutions. Write a balanced chemical equation for the reaction between the NaOH and MgSO 4. Dispose of the solid as instructed by your teacher. Allow the precipitate to settle, then decant the liquid from the solid into a 100-mL graduated cylinder. Slowly pour the Epsom salts solution into the NaOH solution. Mix with another stirring rod until the Epsom salts dissolve. Add 50 ml distilled water to the Epsom salts. Measure about 6 g Epsom salts (MgSO 4 ) and place it in another 150-mL beaker. Mix with a stirring rod until each NaOH pellet dissolves before adding the next pellet.

Add the NaOH pellets to the beaker one at a time. Measure about 4 g NaOH pellets on a balance. Place 50 ml distilled water in a 150-mL beaker. Materials 150-mL beakers (2) 100-mL graduated cylinder stirring rod (2) spatula (2) weighing paper (2) NaOH Epsom salts (MgSO 4 7H 2 O) distilled water balance Procedure 1.
