## Overview

Trustleaf’s 1kg Aluminium Sulphate powder offers 17% iron-free purity, ideal for water purification, textile mordanting, and soil pH adjustment. Perfect for professionals seeking sustainable, multi-functional chemical solutions with proven reliability and organic compatibility.

## Description

Aluminium sulphate is used in water purification and as a mordant in dyeing and printing textiles. In water purification, it causes impurities to coagulate which are removed as the particulate settles to the bottom of the container or more easily filtered. When dissolved in a large amount of neutral or slightly alkaline water, aluminium sulfate produces a gelatinous precipitate of aluminium hydroxide, Al(OH)3. In dyeing and printing cloth, the gelatinous precipitate helps the dye to adhere to the clothing fibres by rendering the pigment insoluble. Can change the colour of hydrangeas by reducing the PH value of soil.
