Lead BromideLead bromide (PbBr₂) is an inorganic compound consisting of lead and bromine. Here are some key details about lead bromide:
Properties:
- Chemical Formula: PbBr₂
- Appearance: White crystalline solid
- Molar Mass: 367.01 g/mol
- Melting Point: 373 °C (703 °F)
- Boiling Point: Decomposes before boiling
- Density: 6.66 g/cm³
- Solubility in Water: Poorly soluble (1.03 g/100 mL at 20 °C)
Structure:
Lead bromide has an orthorhombic crystal structure. In the solid state, PbBr₂ forms a lattice with lead ions surrounded by bromide ions.
Description
Uses of Lead Bromide
1. Chemical Reactions and Synthesis:
- Precipitation Reactions: Lead bromide is commonly used in precipitation reactions to demonstrate the formation of an insoluble salt. For example, mixing lead(II) nitrate (Pb(NO₃)₂) with a bromide salt like sodium bromide (NaBr) yields a precipitate of lead bromide.
- Synthesis of Lead Compounds: It can be used as a precursor in the synthesis of other lead-containing compounds through various chemical reactions.
2. Analytical Chemistry:
- Qualitative Analysis: In qualitative inorganic analysis, lead bromide can be used to confirm the presence of bromide ions in a solution. This is done by adding a solution containing lead ions and observing the formation of a white precipitate of PbBr₂.
- Stoichiometry and Solubility Studies: It is often used in experiments to study stoichiometry, solubility product constants (Ksp), and the effects of common ion and diverse ion effects on solubility.
3. Educational Demonstrations:
- Teaching Material: Lead bromide is used in educational settings to teach concepts such as solubility rules, precipitation reactions, and the properties of ionic compounds.
- Laboratory Experiments: It can be involved in laboratory experiments designed to demonstrate the properties and reactions of lead and bromide compounds.
4. Radiation Detectors:
- Detector Material: Lead bromide is used in the fabrication of certain types of radiation detectors due to its high density and effective atomic number, which makes it suitable for detecting gamma rays and X-rays.
5. Photographic Research:
- Historical Use in Photography: Historically, lead bromide was used in the production of photographic emulsions. While it is less common today due to the advent of digital photography, it may still be studied for its historical significance and properties.

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.
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 Carbonate 250g
Aluminum carbonate is a chemical compound with the formula Al2(CO3)3. It is a white, crystalline solid that is insoluble in water. Aluminum carbonate is not commonly encountered in pure form due to its high instability, especially in the presence of water and carbon dioxide. Instead, it tends to decompose into aluminum hydroxide and carbon dioxide when exposed to moisture or acidic conditions.
