Document Summary

The ksp of calcium hydroxide by titration of. Calcium hydroxide is a soft white caustic powder used in making mortar, cements, calcium salts, paints, and petrochemicals. It is also used in saltwater aquaria to make up kalkwasser/limewater solutions for reef tanks, and is used as a ph regulating agent. Notice that calcium hydroxide is divalent and thus has twice the neutralizing power as molecules like naoh that are monovalent. Calcium hydroxide is manufactured industrially by adding water to calcium oxide (quicklime) in a strongly exothermic reaction: Calcium hydroxide, ca(oh)2, is an ionic solid that is only slightly soluble in water. A calcium hydroxide solution is also referred to as limewater. A saturated solution of calcium hydroxide has the solid in equilibrium with its ions as shown below: Recall that a saturated solution is a solution that contains the maximum amount of dissolved solute possible at a given temperature. (the solution contains undissolved solute in equilibrium with the solution. )
