Usage

Description

Aluminum sulfate, AI2(SO4)3, is a colorless salt composed of monoclinic crystals with a specific gravity of 2.71. It is a common aluminum salt used in astringents and is very similar to aluminum. It is water-soluble and decomposes with the application of heat. One of the commonest hydrates of aluminum sulfate is a hydrate resulting from the formal combination of anhydrous aluminum sulfate with approximately 16 mol eq. of water.

Uses

Used in Astringent Applications:
Aluminum sulfate is used as an astringent agent for its ability to contract body tissues, providing a tightening effect on the skin and mucous membranes.
Used in Manufacturing Dyes:
Aluminum sulfate is used as a key component in the production of various dyes, contributing to their color and stability.
Used in Paint and Varnish Removers:
Aluminum sulfate is utilized as an active ingredient in paint and varnish removers, helping to break down and dissolve these substances, making it easier to remove them from surfaces.
Used in Water Treatment:
Aluminum sulfate is employed in the water treatment industry as a coagulant, aiding in the removal of suspended particles and impurities from water supplies.
Used in Paper Manufacturing:
In the paper industry, aluminum sulfate is used to help control the pH levels of the pulp, which is essential for the proper processing and production of paper products.
Used in Firefighting:
Aluminum sulfate is used in the creation of certain firefighting foams, enhancing their effectiveness in extinguishing fires by increasing their viscosity and adherence to surfaces.
