3 Station 2: H 2 O 2 + NaClO 1.Describe each of these liquids. 2.Measure out 10 mL of H 2 O 2 and pour gently into beaker. 3.Use plastic pipette to extract.5 ML of NaClO. (about half of the pipette) 4.When everyone is ready, squeeze the NaClO into the beaker (do NOT touch pipette to H 2 O 2 or reaction solution) 5.Tell your teacher if you have contaminated the pipette. 6.Write down observations. 7.Gently pour substance into the waste container at your station.
