WebQuestion: using mean titration volumes, calculate the hydroxide concentration in each of the two saturated Ca(OH)2 solutions? Ca(OH)2 mean = 31.09mL and Ca(OH)2+CaCl2*H2O mean = 28.27 mL also, what are the chemical equations for the neutralization of hydroxide ions during titration & equlibrium dissolution of calcium hydroxide? http://www.seas.ucla.edu/~pilon/Publications/RSC%20Advances2024-Calcination%20Free%20Ca(OH)2.pdf
WebMar 28, 2024 · And from there, calcium hydroxide dissociates as: Ca(OH)2(s) ⇌ Ca2+(aq) +2OH−(aq) Therefore, [OH−]eq = 2[Ca2+]eq, and. [OH−]eq = 0.0389 M ≡ 2s. [Ca2+]eq = 0.0195 M ≡ s. As a result, the Ksp is: Ksp = [Ca2+][OH−]2 = s(2s)2 = 4s3. = 4(0.0195)3 = 2.94 ×10−5. The actual Ksp is about 5.5 ×10−6.
