In water treatment, which compound is described as looking like broken glass crystals?

Explanation:
The question trains you to recognize crystal shapes of phosphate compounds used in water treatment. Sodium hexametaphosphate is a polymeric metaphosphate commonly used as a sequestrant and corrosion inhibitor, and when it crystallizes it tends to form irregular, shard-like pieces that look like broken glass. That distinctive glassy, broken-crystal habit is the giveaway for this compound. The other phosphates – orthophosphates and zinc-containing phosphates – tend to form more typical, well-formed crystals and do not have that broken-glass appearance. So the crystal habit described as broken glass points to sodium hexametaphosphate.
