aimed to determine the solubility product constant (Ksp) of Ca(OH)2 as well as to evaluate the effects of common and non-common ions on its solubility. Ca(OH)2 solids were dissolved in eight various media: distilled water‚ 1.0 M KCl‚ 0.5 M KCl‚ 0.1 M KCl‚ 0.05 M KCl‚ 0.005 M KCl‚ 0.001 M KCl‚ and 0.1 M Ca(NO3)2. The concentration of dissociated OH- concentrations was determined by means of titrimetric analysis with 0.1 M HCl. The [OH-] values were then used to calculate the solubility and Ksp of

standardized 0.05 M solution of HCl was titrated into a 25 mL solution of saturated Ca(OH)2 which contained 2 drops of orange methyl identifier. Once the titration began‚ the HCl was added until the methyl orange endpoint was reached‚ and as a result the volume of the HCl needed for the endpoint to be reached could be used in determining the moles and in turn the molar solubility and the solubility constant of the Ca(OH)2. For the second part of the experiment a common ion (CaCl2) was added to the calcium

If a reaction step is multiplied by a common coefficient n‚ the new equilibrium constant is raised to the nth. The first part of the experiment dealt with the equilibrium reaction Cu(OH)2(s) ⇌ Cu2+(aq) + 2OH-(aq). 0.10 M Cu(NO3)2 and 0.10 M NaOH were reacted together in seven test tubes to form the solid Cu(OH)2‚ a blue precipitate. Distilled water was added to the first test tube. This served as the control. When 6.0 M H2C2O4 was added to the second test tube‚ the precipitate turned cloudy

solution of Ca(OH)2 will be made by reacting calcium metal with water‚ then filtering off the solids: Ca(s) + H2O → Ca(OH)2(s) Ca2+(aq) + 2OH-(aq) The concentration of dissolved hydroxide will be determined by acid-base titration with standardized HCl solution. The Ksp for Ca(OH)2 will be calculated from the experimentally determined saturation concentration of hydroxide. Objectives of the data analysis understand solubility equilibria‚ acid-base neutralization‚ and the chemistry of lime (Ca(OH)2)‚ limewater
