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... WebKsp = 5.61 × 10 − 12 When acid is added to a saturated solution that contains excess solid Mg (OH) 2, the following reaction occurs, removing OH − from solution: H + (aq) + OH − (aq) → H2O(l) The overall equation …

So the molar solubility …
WebFeb 4, 2024 · The pH scale ranges from 0 to 14. A low pH value indicates acidity, a pH of 7 is neutral, and a high pH value indicates alkalinity. The pH value can tell you whether you're dealing with an acid or a base, but it … WebThe Ksp expression would be: Ksp = [Ag+]2 [SO42-] I don't think you should have any more trouble with these as long as you follow the simple rules: 1. leave out the solid. (Include the aqueous ions only) 2. change coefficients in the balanced equation to exponents in the Ksp expression. ***** Calculating Solubility given Ksp .
WebKsp = [Mg2+] [OH-]^2 = [.12+s] [2s]^2. 1.2 * 10^-11 = [.12+s] [2s]^2. solve for s. [OH-] = 2*s (as we said above) …and you should be able to find pH from [OH-] by way of pOH. Feel free to … Solution: 1) The chemical equation: Mg(OH)2⇌ Mg2++ 2OH¯ 2) The Kspexpression: Ksp= [Mg2+] [OH¯]2 3) Use the pH to get the pOH: 14.00 - 10.17 = 3.83 4) Use the pOH to get the [OH¯]: [OH¯] = 10¯pOH= 10¯3.83= 1.479 x 10¯4M 5) From the chemical equation, we note that the [Mg2+] is half the value of the [OH¯], therefore:
