Acetic acid is an organic acid with the chemical formula CH3COOH, also known as ethanoic acid. It is a colorless liquid with a pungent, sour taste and a distinctive vinegar-like odor. Acetic acid is an important industrial chemical used in the production of various products, including solvents, plastics, textiles, and food additives. It is also the main component of vinegar, which is commonly used as a condiment and preservative in cooking and food preparation.
Description
Acetic Acid
In laboratory settings, acetic acid finds several applications:
- Solvent: Acetic acid is often used as a solvent for various organic compounds, particularly those that are polar or partially polar. It can dissolve a wide range of substances, making it useful for extraction and purification processes.
- Reagent: Acetic acid is commonly used as a reagent in various chemical reactions. For example, it’s used in the synthesis of esters through Fischer esterification reactions. It’s also used in the production of acetic anhydride, a versatile reagent in organic synthesis.
- pH Adjustment: Acetic acid is a weak acid, and its solution can be used to adjust the pH of other solutions. Since it’s a weak acid, it’s less likely to cause drastic changes in pH compared to strong acids like hydrochloric acid or sulfuric acid.
- Titration: Acetic acid solutions are often used in acid-base titrations, especially for the titration of weak bases or as a standard solution in the determination of unknown concentrations of acids or bases.
- Preservative: In microbiological laboratories, acetic acid solutions are sometimes used as preservatives for samples. Its antimicrobial properties help prevent the growth of contaminants in certain types of samples.
- Cleaning: Dilute acetic acid solutions can be used for cleaning laboratory glassware, particularly to remove mineral deposits or organic residues.
- Staining: Acetic acid is used in some staining techniques, especially in histology, to help fix and preserve cellular structures in tissues.

Aluminum Ammonium Sulphate
Aluminum ammonium sulfate, also known as ammonium alum or just alum, is a chemical compound with the formula (NH4)Al(SO4)2Ā·12H2O. It's a white crystalline solid commonly used in water purification, leather tanning, and as a mordant in dyeing textiles.
In water purification, alum acts as a coagulant to remove impurities by causing suspended particles to clump together, making it easier for filtration to remove them. In leather tanning, it helps to stabilize the leather by tightening the collagen fibers. And in dyeing textiles, alum helps the dye adhere to the fabric.
However, it's important to note that excessive exposure to aluminum compounds like alum can be harmful, so it's typically used with caution and proper safety measures.
