Aluminum sulfate

Aluminum sulfate is a chemical compound often used in various industries, including water treatment, paper manufacturing, and as a food additive. In water treatment, it helps remove impurities by causing particles to clump together so they can be easily filtered out. In gardening, it can lower soil pH to make it more acidic, which is beneficial for certain plants. Additionally, it's used in the production of fireworks and as a mordant in dyeing processes. Aluminum sulfate is generally recognized as safe in small amounts, but proper handling is important due to its chemical properties.
