Properties. Calcium hydroxide is relatively insoluble in water, with a solubility product Ksp of 5.5 × 10−6. It is large enough that its solutions are basic according to the following reaction: Ca(OH)2 → Ca2+ + 2 OH.

Molar Solubility. A substance's solubility product (Ksp) is the ratio of concentrations at equilibrium. Molar solubility, which is directly related to the solubility product, is the number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated.

Carbon dioxide reacts with limewater (a solution of calcium hydroxide, Ca(OH) 2), to form a white precipitate (appears milky) of calcium carbonate, CaCO 3. Adding more carbon dioxide results in the precipitate dissolving to form a colourless solution of calcium hydrogencarbonate.

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. The solubility decreases with increasing temperature. The suspension of calcium hydroxide particles in water is called milk of lime.

Ca2+ represents an ion with 20 protons and 18 electrons. A calcium atom has 20 protons and 20 electrons. The 2+ charge next to the symbol indicates a loss of two electrons: 20-2=18. When atoms form ions, they lose or gain electrons.

Calcium, Ca Calcium is also in Group 2. It has two electrons in its outer shell. When these electrons are lost, a calcium ion, Ca 2+, is formed. A calcium ion has the same electronic structure as an argon atom (Ar).
