The purpose of both is to inhibit bacterial growth. The media is used for growing fungi.
rose bengal inhibits growth of bacteria, thus promoting the growth of fungi, mold and yeast.
The purpose of adding iodine solution to the onion cell is to stain the cell's starch granules. Starch granules will appear blue-black when iodine solution is added, allowing for easy visualization of the presence of starch in the cell.
Adding a base
Adding water to a base can help to dissolve or dilute substances, adjust the pH level, increase the volume of the solution, or facilitate certain chemical reactions. It can also help to control the temperature during a reaction or to provide a medium for mixing and stirring.
When adding a strong acid to an acidic solution pH decreases. Adding a strong base to an acidic solution the pH increases.

Adding NaCl solution to soap mixture helps to precipitate out the soap, making it easier to separate from the rest of the solution. This process is known as salting out and helps concentrate the soap for further processing.

Adding a base
The purpose of titrating sodium hydroxide with an acid solution is to determine the concentration of the acid solution. By carefully adding the acid solution to the sodium hydroxide until the reaction reaches equivalence, the amount of acid needed can be used to calculate its concentration.
Indicators contain chemicals that will react with certain substances. If that substance is present in your unknown solution, a reaction will occur. If no reaction occurs, then that substance is not present in your solution
Adding NaCl solution to the soap mixture helps to separate the soap from the aqueous solution. This process is called salting out, where the addition of salt reduces the solubility of the soap, causing it to precipitate out of the solution.
Adding water to a base can help to dissolve or dilute substances, adjust the pH level, increase the volume of the solution, or facilitate certain chemical reactions. It can also help to control the temperature during a reaction or to provide a medium for mixing and stirring.
Hexane is a nonpolar solvent that helps extract nonpolar compounds, such as halogens, from an aqueous solution. By adding hexane, the halogens will preferentially dissolve in the nonpolar layer, allowing for easier separation and purification of the halogens from the aqueous solution.
dilute.
To find the __________ solution when adding vectors, simply draw and label the given information..... graphical.
The purpose of a titration experiment is to determine the concentration of a substance in a solution by reacting it with a solution of known concentration. This is achieved by carefully adding the titrant to the analyte until the reaction reaches a neutral point, known as the equivalence point. Titration is commonly used in chemistry to quantify acids, bases, and other substances in a sample.
