Its alcohol so it can purify the chemicals used in the experiment. Furthermore, it will travel up the filter paper better than water will. Ethanol is pure whereas water may have other things in it such as chlorine is in tap water
Polar and non-volatile compounds, such as large biomolecules like proteins or carbohydrates, can be separated by high performance liquid chromatography but not gas chromatography due to differences in their chemical properties and interaction with the stationary phase. Gas chromatography is more suitable for separating volatile and non-polar compounds based on their volatility and interaction with the stationary phase.

No, they are different techniques.
The purity of recovered ethanol can be determined by conducting a distillation test to separate out impurities and measure the ethanol content. The purity can also be verified using methods such as gas chromatography or mass spectrometry to analyze the chemical composition of the recovered ethanol. Testing the specific gravity or conducting a simple flame test can also indicate the presence of impurities in ethanol.
You can measure ethanol content after fermentation using a variety of methods, such as gas chromatography, distillation, or using a hydrometer. Each method has its own advantages and limitations, so choose the one that best fits your needs and resources. Be sure to follow proper protocols and safety measures when handling ethanol.
Gas chromatography and mass spectrometry are the confirmatory tests used to detect ethanol in biological samples. These tests are highly specific and sensitive, allowing for accurate quantification of ethanol levels in a sample. Additionally, enzymatic assays can also be used for confirmation of ethanol presence.

Water is preferred over ethanol for chromatography because it is more polar and can interact with a wider range of compounds, providing better separation. Additionally, water is a safer and more environmentally friendly solvent compared to ethanol.
