Agar agar powder refers to the dehydrated and powdered form of agar agar, a natural gelling agent derived from seaweed. It is made by drying and grinding the agar agar gel, resulting in a fine powder with excellent gelling properties. Agar agar powder is commonly used in cooking, baking, and food preparation as a vegetarian and vegan substitute for gelatin. It is prized for its ability to create firm and stable gels at relatively low concentrations and temperatures. Agar agar powder is versatile and can be used in a variety of recipes, including desserts, confectioneries, jams, jellies, and savory dishes.

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

Ammonium chloride is an inorganic compound with the chemical formula NH4Cl. It is a white crystalline salt that is highly soluble in water and has a salty taste. Ammonium chloride is often used in various industrial and laboratory applications, including as a flux in soldering, as a nitrogen source in fertilizers, and as a component in dry cell batteries. It can also be used in medicine as an expectorant to help thin and loosen mucus in the respiratory system

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.
