(Except where otherwise noted, 2 pts for all blanks, boxes and questions.) Give the balanced equation for the solvation of Ca(OH)2 in water. CaloH), 15) H₂011) (at laq) + 2014 laq) Write the solubility-product expression, Kap, for Ca(OH)2. Ksp [cat] [OH-]2 Explain in complete sentences using equations if necessary for illustration. 1. What is the stoichiometric relationship of the hydroxide ion concentration to calcium ion concentration? [OH-] = [Ca ] 2. What is the stoichiometric relationship of the solubility of Ca(OH)2 to the concentration of OH' in solution? [Ca (014), ) - 20Hº] 3. What is the stoichiometric relationship of the solubility of Ca(OH)2 to the concentration of Ca²+ in solution? [Ca (OH)2) = [cat] 4. Using LeChatlier's Principle what is the predicted effect of the addition of the common ion, Cat, on the solubility of Ca(OH)2? remember lal).(s)(1). With the addition of actions, it will decrease the solubility of CaloH)2 by shifting the equilibrium towards the left side. 5. What is the expected effect of the addition of the common ion on Ksp? The expected effect of the addition of the common in on k sp is that the ksp vlue is not effected by the common ion because it is an equilibrium constant. 6. Write the balanced equation for the neutralization of calcium hydroxide by hydrochloric acid. Ca(OH)₂ (s) + 2HCl laq) (all laq) + 2H₂0 1 l

Answer 1

11 hart Your experimental solubility for this Values are required. The Values you got must be in accordance with & Le-chattier principle If you have added some common ion, it must decrease solubility of Caloth. (2) Calor Ca2+ d2017 Naoh - Nat ti OH Commonion Due to common in effect of OH hrodued from ta Naoh, solubility of Caloh) will decrease and equilibrium will shift is left direction (Reactant Side). 3) Calon 1 Ca2+ + 2011 Nach Nat tice Ca²+ + 20 Cach₂ Ca²+ ions will react with or of Nace thereby producing Cally. Thus, more and more Ca²+ would be foroduced implizing Calore solubility will Increase
