WebSolution: 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: WebFeb 10, 2024 · Explanation: And so when calcium hydroxide is placed in water....the solubility is governed by the equilibrium expression... Ksp = [Ca2+][H O−]2. And so if we represent …

WebAspirin is acetylsalicylic acid, CH 3 CO 2 C 6 H 4 CO 2 H. The −CO 2 H functional group is still present, but its acidity is reduced, K a = $3.0×10^{-4}$. What is the pH of a solution of aspirin with the same concentration as a saturated solution of salicylic acid (See Part a). WebEven though Ca(OH) 2 is an inexpensive base, its limited solubility restricts its use. What is the pH of a saturated solution of Ca(OH) 2? Under what circumstances, if any, does a sample of solid AgCl completely dissolve in pure water? Solution. hemtex dukar runda
