Calcium Hypochlorite
هيبوكلوريت الكالسيوم
Chlorine bleach (solid)
The verdict
Solid chlorine bleach — same 'never mix' rules; an oxidiser too. Handle carefully.
What it is
Solid 'bleaching powder' / pool chlorine.
The solid form of chlorine bleach — same chlorine chemistry, same deadly mixing rules (acids → chlorine gas, ammonia → chloramine), plus it's an oxidiser that can ignite organics. Powerful for pools and heavy disinfection, but needs careful, ventilated, never-mixed handling.
