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 Potassium Sulphate, commonly known as potassium alum or potash alum, is a chemical compound with the formula KAl(SO₄)₂·12H₂O. It is a type of alum, a double sulfate salt, and is typically found in its dodecahydrate form. Here are some key points about this compound:

Physical Properties:

• Appearance: Colorless, transparent crystals or white powder.
• Solubility: Soluble in water but insoluble in alcohol.
• Melting Point: Decomposes at high temperatures before melting.

Chemical Properties:

• Molecular Formula: KAl(SO₄)₂·12H₂O
• Molecular Weight: 474.39 g/mol (for the dodecahydrate form)
• Acidity: It is slightly acidic in aqueous solution.

An ammonia solution is a solution of ammonia (NH3) gas dissolved in water. It is a clear, colorless liquid with a pungent odor and a basic pH. The concentration of ammonia in the solution can vary, and is typically expressed in terms of percent by weight or by volume. Ammonia solutions are commonly used in a variety of applications, including cleaning agents, fertilizers, and as a precursor to other chemicals. They are also used in industrial processes such as refrigeration, gas purification, and water treatment. Ammonia solutions can be dangerous if not handled properly, as they are highly corrosive and can release toxic fumes if mixed with certain chemicals

Anhydrous aluminum chloride, often represented as AlCl3, is a chemical compound composed of aluminum and chlorine. "Anhydrous" means it lacks water molecules in its structure. It's a white or pale yellow solid that is highly hygroscopic, meaning it readily absorbs moisture from the air. This property makes handling it a bit tricky since it can form a solution with water vapor in the air, turning into a fuming liquid.
