25 mL of a 0.126 M solution of Ba(OH)2 is titrated with a solution of HCl of unknown molarity. If the equivalence point of the titration is obtained after addition of 28.3 mL of the HCl, the molar concentration of HCl is: Ba(OH)2 + 2 HCl = 2 H2O + BaCl2 A. 0.134 M B. 0.252 M C. 0.285 M D. 0.223 M E. 0.063 M
To calculate the concentration of a solution using acid–base titration data. In an acid–base titration, an acid (or base) of known concentration is added to a base (or acid) of unknown concentration until the number of moles of H+ and OH- are equal, a condition called the equivalence point. Since you know the number of moles of H+ (or OH- ) that you added, you can determine the number of moles of OH- (or H+) in the unknown solution. For...
A 15.00 mL sample of nitric acid, HNO3, requires 0.655 g of barium hydroxide, Ba(OH)2 for titration to the equivalence point. What is the concentration of the nitric acid? 2 HNO3(aq) + Ba(OH)2(aq) → Ba(NO3)2(aq) + 2 H2O(l)
