Equation for Calcium Hydroxide Dissolving in Water | Ca (OH)2 + H2O. Watch later 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. The solubility decreases with increasing temperature solubility changes with temperature. ksp is another form of equilibrium expression that deals with solubility. The reaction that will take place is: Ca(OH) 2 Ca 2+ + 2 OH-The ksp was determined by taking the calcium hydroxide and titrating it with a known concentration of HCl.
