To prepare indicators from plants, you can crush or grind the plant material and extract the pigment using a solvent like ethanol or water. The extracted solution can then be used to test for specific pH ranges by observing color changes in the presence of acids or bases. Some common plant-based indicators include red cabbage, turmeric, and beets.

Yes. Almond Extract, Anise Extract, and Lemon Extract have high alcohol content (60%-80%) You can get drunk off of it, but it will taste horrible. Prepare to be in extreme discomfort after drinking.
A ready available blend of cumin, coriander, black pepper, and turmeric. One can prepare it at home by mixing equal parts of cumin and coriander, and adding a dash of black pepper and turmeric. Grinding the spices together will help to even out the texture and ensure even distribution of all the flavors.
Common solvents used for gas chromatography calibration include hexane, methanol, acetone, and chloroform. These solvents are often used to prepare standard solutions at known concentrations for calibrating the gas chromatograph and for determining the retention times of analytes.
Gas chromatography (GC), is a common type of chromatography used in analytical chemistry for separating and analysing compounds that can bevaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also be determined). In some situations, GC may help in identifying a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture.

Iron chloride impurity may arise in chromatography due to its presence in the sample or from contamination in the solvent or column material. It can cause interference with the separation process and lead to inaccurate results. Proper precautions should be taken to minimize the presence of impurities in chromatography experiments.
Studding the onion with the cloves makes it easier to extract the cloves at the end of the preparation.
We need to prepare sodium extract for the detection of foreign elements because foreign elements are found in organic compound bonded covalently. As a result they cannot be detected through organic compound directly. Hence they are first converted into ionic compound with the help of sodium extract

To prepare para-aminophenol, you can start by nitration of phenol, followed by reduction of the nitro group to an amino group. You can then isolate para-aminophenol by separating it from other byproducts using techniques such as recrystallization or column chromatography. It is also important to maintain appropriate safety precautions, as both nitration and reduction reactions can be hazardous.
