11 08 2010The equilibrium explanation is that one mole of calcium hydroxide dissociates into one mole of Ca +2 and two moles of OH- According to Le Chatlier's Principle if stress is applied then the system will try to alleviate the stress Because two moles of OH- are produced per mole of Ca(OH)2 adding OH- will have a greater effect on solubility than adding Ca +2 so less will be able to dissolve

The solubility product expression describes Your primary objective in this experiment is to test a saturated solution of calcium hydroxide and use your observations a nd measurements to calculate the K s p of the compound You will do this by titrating the prepared Ca(OH) 2 solution with a standard hydrochloric acid solution By determining the molar concentration of dissolved hydroxide

Solubility of Organic Compounds

The solubility of carboxylic acids (pKa = 3 to 5) and phenols (pKa = 9 to 10) in aqueous hydroxide is due to the formation of the polar (ionic) carboxylate or phenoxide groups since they are much stronger acids than water (pKa about 15) and therefore the acid-base equilibria lie far to the right (products) which is the more polar side: RCO 2 H + OH RCO 2 + H 2 O ArOH + OH ArO + H 2 O SOL
