Cobalt chloride + Sodium hydroxide

There’s a whole universe forming in there.

saline chlorination where instead of chlorine the salt is generated into chlorine by a chlorinator

Cobalt(II) chloride (CoCl₂) is a soluble salt in water, meaning it dissociates into Co²⁺ (cobalt ions) and Cl⁻ (chloride ions). Sodium hydroxide (NaOH) also dissociates in water, breaking into Na⁺ (sodium ions) and OH⁻ (hydroxide ions). When these two solutions are mixed, a double displacement reaction occurs. The cobalt ions (Co²⁺) combine with hydroxide ions (OH⁻) to form cobalt(II) hydroxide (Co(OH)₂), which is a solid precipitate. This happens because Co(OH)₂ is not soluble in water. Meanwhile, the sodium ions (Na⁺) combine with chloride ions (Cl⁻) to form sodium chloride (NaCl), which remains dissolved in the water.

in this metathesis (double displacement) precipitation reaction, cobalt II chloride reacts with sodium hydroxide to produce sodium chloride, and the very interesting, solid blue cobalt II hydroxide precipitate

Carved by Hans Schwarz in 1520, “Death and the Maiden” is a boxwood medallion currently housed at the Bode Museum in Berlin. The theme, originating in late medieval and Renaissance art, reflects on the juxtaposition of life and death. This motif was especially poignant during times of plague and war, when death was a pervasive part of everyday life.

I’ve seen this before…
