Cresol Red is a pH indicator dye commonly used in titrations and other laboratory experiments to determine the pH of a solution. It changes color based on the acidity or basicity of the solution it is in. Here are its key characteristics:
- Chemical Structure: Cresol Red is a sulfonephthalein dye with the molecular formula C21H18O5S.
- Color Change: It transitions from yellow in acidic solutions (pH < 1.8) to red in neutral solutions (pH around 7.0), and then to purple in basic solutions (pH > 8.8).

Aluminum Ammonium Sulphate
Aluminum ammonium sulfate, also known as ammonium alum or just alum, is a chemical compound with the formula (NH4)Al(SO4)2·12H2O. 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.
Aluminum Hydroxide 250gm
Aluminium hydroxide is a chemical compound with the formula Al(OH)3. It is an inorganic compound that is commonly used as an antacid to neutralize excess stomach acid, as well as a component in the manufacture of various products, such as ceramics, paper, and cosmetics. It is a white, powdery substance that is insoluble in water and has a low toxicity. When heated, it decomposes to produce aluminium oxide, or alumina, which is used in the production of aluminium metal.
