Description
"Laboratory Preparation and Properties of Oxygen" PPT courseware
Purpose:
1. Master the principles and experimental equipment of producing oxygen in the laboratory.
2. Preliminarily learn how to use hydrogen peroxide to produce three bottles of oxygen, and verify the properties of oxygen.
think:
What problems do we need to solve when producing oxygen in the laboratory?
Activity 1: Selection of instruments and devices
1. The generation device selected to produce oxygen using hydrogen peroxide ( )
Collection device ( )
Summary: When going to the laboratory to prepare gas
Basis for selecting generator (state of reactants and reaction conditions)
Basis for selecting collection device (water solubility and density of gas)
Activity 2: Exploration on producing and collecting oxygen
Group experiment
Let's make and collect three bottles of oxygen together
Kind tips:
1. Take half a spoonful of manganese dioxide.
2. Hydrogen peroxide (20-25 ml) is corrosive to a certain extent, so be careful when using it; pay attention to safety when working in a group.
3. When there is no medicine in the separatory funnel, the piston must be closed in time.
4. When using the third gas collecting bottle to collect oxygen, a small amount of water remains in it. The collected oxygen will be used in later experiments.
Can you try to explain it from a micro perspective?
For a reaction to occur between molecules, the primary condition is contact and collision between molecules. In the air, nitrogen is more abundant and oxygen molecules are relatively less. The chance of collision between charcoal and oxygen molecules is small, but in pure oxygen, the chance of collision is greatly increased.
Extracurricular exploration
Use the materials around you (plastic bottles with stoppers, syringes, milk straws, glasses, etc.) to make a simple oxygen production device by yourself.
did you do it
1. Can the bubbles that just emerge when collecting oxygen by drainage method be collected immediately? Can you tell me why?
2. Is the oxygen-filled gas bottle placed on the table? Can you tell me why you want to be square?
3. Can you judge that a bottle of oxygen is full? Have you mastered the method of fullness verification?
