So that's equal to 0.000422 moles of barium hydroxide. 2HNO3 (aq) + Sr (OH)2 (aq) -> 2H2O (l) + Sr (NO3)2. So you have hydrochloric acid, and calcium hydroxide, a common base that requires 2 equivalents of acid for stoichiometric reaction: #Ca(OH)_2(aq) + 2HCl(aq) rarr CaCl_2(aq) + 2H_2O(l)#. Ionization energies fall down the group. Direct link to Matt B's post That simply tells you how, Posted 4 years ago. The reaction will be Sr(OH)_2 + 2HCl -> SrCl_2 + 2H_2O the volume of strontium hydroxide is "315 mL" the volume of hydrochloric acid is "525 mL" the molarity of hydrochloric acid is "0.80 M" Steps: The number of moles of HCl consumed in . Because there are two moles of OH in each mole of Sr(OH) 2, 0.10 mol of Sr(OH) 2 is needed to react completely. In fact, we can even be more concise than this because the calcium salts are present in solution as #Ca^(2+)(aq)# and #X^(-)(aq)#, and these are simply along for the ride. What was the pH indicator used for this titration? So, we can say that mL were used simply because the information was given in mL and it would have been unecessary to change.
