A Double Salt in Solution
In water, potash alum separates completely into K+, Al3+ and SO4 2- ions, so each ion gives its own test; that is what marks it as a double salt rather than a complex salt. The solution is slightly acidic, because the hydrated aluminium ion hydrolyses, and it turns blue litmus red.
Crystals and Coagulation
A small seed crystal hung on a thread in a saturated solution that cools slowly grows into a clear octahedron. In muddy water, a little alum makes the fine clay clump and settle, because the triply charged aluminium ion neutralises the negative charge on the colloidal particles; this is the classic illustration of the Hardy–Schulze rule.
