WebApr 30, 2024 · Ksp = [Ca 2+ ] [OH-] 2. Since there is a common ion present (Ca2+) provided by the added CaCl2, we know the [Ca2+] = 0.2 M. The molar solubility is given as 0.0026 M and since you get 2 OH- from each Ca (OH)2, the molar solubility of OH- will be 2 x 0.0026 M = 0.0052 M. Plugging these values into the Ksp expression, we obtain... WebOct 26, 2024 · For saturated aqueous solution of calcium hydroxide (ca (oh)2) pH = 12.25 ⇒14 - pOH = 12.25 ⇒ pOH = 1.75 ⇒- log [OH-] = 1.75 ⇒ log [OH-] = - 1.75 ⇒ [OH-] = 10^ (-1.75) ⇒ [OH-] = 0.01778 M which is the concentration of OH- ions in a solution On ionization in the water Ca (OH)2 gives us two separate ions which are 1 Ca2+ ion and 2 OH- ions.
