Explanation

CO2
- The orsat apparatus is used to measure the concentration of carbon dioxide in a gas sample. It allows for the precise analysis of gases by absorbing the carbon dioxide present in the sample.

Orsat Apparatus
- The orsat apparatus is a device specifically designed for gas analysis. It consists of various components such as absorption bulbs, pipettes, and leveling bottles, which are used to measure the concentrations of different gases in a sample.

CO
- The orsat apparatus can also be used to measure the concentration of carbon monoxide in a gas sample. By passing the gas through specific reagents in the absorption bulbs, the amount of carbon monoxide can be determined accurately.

O2
- Similarly, the orsat apparatus can be utilized to measure the concentration of oxygen in a gas sample. This is crucial for various industrial processes where the presence of oxygen needs to be monitored and controlled.
In conclusion, the orsat apparatus is a versatile tool for gas analysis, allowing for the measurement of various gases such as carbon dioxide, carbon monoxide, and oxygen in a sample.
