Add 50ml of concentrated sulfuric acid with a density of 1.84g/cm3 in the 250ml distilled bottle, and 10ml of methic acid with a density of 1.2g/cm3 in the split funnel. The device is shown in the figure. Check the air tightness of the device.
Heat the concentrated sulfuric acid to 80 ~ 90 ° C and remove the alcohol lamp. 3. Add methic acid to the bottle to the bottle, which is generated by carbon monoxide. 4. When the air is exhausted, collect carbon monoxide with drainage method and collect the gas cylinder with a rubber plug. (The first bottle of carbon dioxide gas is mixed with air, and it will burst when ignited. Pay attention to safety.)
The two of carbon monoxide production [principle] 2C+O2 2CO2 CO2+C 2CO [Products] Iron frame, combustion tube, glass fiber, activated carbon, oxygen bag, alcohol lamp. [Operation] 1. Take a combustion tube of 20 × 350mm, put a small amount of glass fiber at the tube, and add about 4/5 of the granular activated carbon. The device is shown in the figure.
The burning tube was sandwiched on the iron frame, and the flames of the alcohol lamp were heated at the end of the combustion tube until the drums were drummed into the carbon particles in the burning tube to burn. At this time, the flames were removed, the burning tube was quickly vertically, fixed on the iron frame, and the oxygen was slowly bulged into the iron frame. The charcoal layer continued to burn and emit light. 3. Use a small test tube to collect the gas from the pointed glass tube, check the purity, and then ignite at the mouth of the tube. You can see the light blue flame burning carbon monoxide. [Remarks] This experiment generates carbon monoxide to ignite or restore copper oxide. 2. The airflow rate of oxygen should not be too large to prevent carbon dioxide that is more generated. You can use a spiral clip to control the flow rate of oxygen. 3. After several experiments, the charcoal grains should be poured out, the ashes are removed, the carbon particles are supplemented, or the charcoal particles are washed with water, and then used after drying.
