Ca(OH) 2 is quite soluble in glycerol and acids, but only slightly soluble in water. There are many commercial uses for this compound because it readily forms solutions with other substances like silicates. Potassium and bromide are a nonacidic cation and a nonbasic anion respectively. In fact, calcium hydroxide is a strong base, which means that what little does dissolve, dissociates completely. Solubility of calcium and calcium compounds Elementary calcium reacts with water. The solubility decreases with increasing temperature. If you do not find the exact resolution you are looking for, then go for a native or higher resolution. The solubility decreases with increasing temperature. Reacts violently with acids, halogens and metals. … Reacts with water. Solubility Product Constants near 25 °C. Preparation of Calcium Oxide: Calcium oxide, CaO, is obtained by the thermal decomposition of calcium trioxocarbonate(IV). The suspension of calcium hydroxide particles in water is called milk of lime. Experimental Solubility: Soluble in water with generation of heat, and forming Ca(OH)2, in acids, glycerol. Its chemical formula is CaO. When heating calcium hydroxide to 512 °C the calcium hydroxide decomposes into calcium oxide and water: Ca(OH) 2 CaO + H 2 O. Ca(OH) 2 is only slightly soluble in water (0.16g Ca(OH) 2 /100g water at 20°C) forming a basic solution called lime water. Aluminum hydroxide Al(OH) 3 1.8×10 –5. In fact, CaO is somewhat soluble in water. When placed in water, CaO is hydrated to form Ca(OH)2 and Ca(OH)2 is sparingly soluble in water. Industrially, lumps of limestone are heated strongly in a furnace called a lime kiln leading to the decomposition of the limestone at around a temperature of 900 C to yield calcium oxide and carbon(IV) oxide.
