WebSep 20, 2024 · (a) a sample of solid ca(oh)2 is stirred in water at 30°c until the solution contains as much dissolved ca(oh)2 as it can hold. a 100.-ml sample of this solution is withdrawn and titrated with 5.00 10-2 m hbr. it requires 48.8 ml of the acid solution for neutralization. what is the molarity of the ca(oh)2 solution? WebWrite the balanced molecular, total ionic, and net ionic equations for the following reaction. Ca (OH)2 (aq) + HC2H3O2 (aq) arrow. Identify the equation as a molecular equation, a complete ionic equation, or a net ionic equation. OH- (aq) + H+ (aq) arrow H2O (l)

WebIn the titration, the reaction is: 2 H C l + C a ( O H) X 2 = C a C l X 2 + 2 H X 2 O. The acid to base ratio is 2: 1, or (moles acid used) = 2 (moles base used), so M a V a = 2 M b V b, where M is the molarity and V is the volume expressed in liters. Then. M b = M a V a 2 V b. M b = 0.05 M × 0.02 L 2. WebSince we need 2 mol HBr for every 1 mol Ca(OH)2, we can see that there is more than 2 mol of HBr for every 1 of Ca(OH)2 (0.29 mol x 2 = needed HBr = 0.58 mol HBr needed). HBr is in excess, and Ca(OH)2 is therefore the limiting reactant. small christmas gift boxes
