Its solubility increases from 0.66 g/L at 100 °C to 1.89 g/L at 0 °C. [8] Its solubility product K sp of 5.02 × 10 −6 at 25 °C, [1] its dissociation in water is large enough that its solutions are basic according to the following dissolution reaction: Ca(OH) 2 → Ca 2+ + 2 OH −. The solubility is affected by the common-ion effect. Its ...

3 / 8 S 8 + H 2 O + 2 Ca(OH) 2 → 2 H 2 S + CaSO 3 1 / 2 S 8 + 2 H 2 O + 2 Ca(OH) 2 → 3 H 2 S + CaSO 4. However, elemental sulfur can undergo a disproportionation reaction, also called dismutation. The first reaction resembles a disproportionation reaction. The inverse comproportionation reaction is the reaction occurring in the Claus ...
Scrubbing with limestone follows the following idealized reaction: SO 2 + CaCO 3 → CaSO 3 + CO 2. Scrubbing with hydrated lime follows the following idealized reaction: [4] [5] SO 2 + Ca(OH) 2 → CaSO 3 + H 2 O. The resulting calcium sulfite oxidizes in air to give gypsum: 2 CaSO 3 + O 2 → 2 CaSO 4. The gypsum, if sufficiently pure, is ...

Calcium hydrosulfide is the chemical compound with the formula Ca(HS) 2 or CaH 2 S 2. [1] It is formed from the reaction of calcium hydroxide or calcium carbonate with hydrogen sulfide: [2] Ca(OH) 2 + 2H 2 S → Ca(HS) 2 + 2H 2 O CaCO 3 + 2H 2 S → Ca(HS) 2 +H 2 O+CO 2
In that process sodium sulfide reacts with calcium carbonate: [1] Na 2 S + CaCO 3 → CaS + Na 2 CO 3. Millions of tons of this calcium sulfide byproduct was discarded, causing extensive pollution and controversy. [2] Milk of lime, Ca(OH) 2, reacts with elemental sulfur to give a "lime-sulfur", which has been used as an insecticide.
The reaction Ca(OH) 2 + CO 2 ⇌ Ca 2+ + HCO − 3 + OH − illustrates the basicity of calcium hydroxide. Soda lime, which is a mixture of the strong bases NaOH and KOH with Ca(OH) 2, is used as a CO 2 absorbent.
