Bio Neutralization Lab

Experiment 1: Neutralization of Acids and Bases

In this experiment, you will learn how to properly neutralize and dispose of acidic and basic solutions.

|Materials |  |

|5 mL 4.5% Acetic Acid (vinegar), C2H4O2 |4 Weigh Boats |

|(1) 10 mL Graduated Cylinder |*Water |

|8 Litmus Test Strips (Neutral) | |

|Permanent Marker | |

|2 Pipettes | |

|1 g Sodium Bicarbonate (baking soda), NaHCO3 | |

Procedure

1. Use the permanent marker to label three of the weigh boats ad A - C.

2. Measure and pour approximately 5 mL of water into weigh boat "A".

3. Add 0.5 g sodium bicarbonate to weigh boat "B".

4. Measure and pour approximately 5 mL of water into weigh boat "B". Gently pipette the solution up and down until the sodium bicarbonate is fully dissolved in the water.

5. Measure and pour 5 mL acetic acid solution to weigh boat "C".

6. Use the litmus test strips to determine if the substances in weigh boats A - C are acidic or basic. This is accomplished by briefly dipping an unused strip of the litmus paper in each of the weigh boats....
