The Manufacture of Aluminium Sulfate

Aluminium sulfate (Al2(SO4)3), commonly called alum, is produced as white crystals which are non-combustible and soluble in water. This ‚dry™ hydrate (Al2(SO4)3.14H2O) is 17% Al2O3 and is also sold as a 47% w/w aluminium sulfate solution which is 8% Al2O3. It is also sold in solid form as kibbled, ground or dust. Uses of aluminium sulfate

Regents Chemistry Exam Explanations January 2017

The hydrangea is a flowering plant. The color of the flowers it produces can change depending on the pH value of the soil in which the plant grows. Adding aluminum sulfate makes the soil more acidic and adding calcium hydroxide makes the soil more basic. A student performed an experiment by varying soil pH and recording the color of the flowers.
