An analytical chemist performs a titration to determine the concentration of a hydrochloric acid, HCl\text{HCl}HCl, solution. The reaction between barium hydroxide, Ba(OH)2\text{Ba(OH)}_2Ba(OH)2, and hydrochloric acid is given by the equation:
Ba(OH)2(aq)+2HCl(aq)→BaCl2(aq)+2H2O(l) \text{Ba(OH)}_2(\text{aq}) + 2\text{HCl}(\text{aq}) \rightarrow \text{BaCl}_2(\text{aq}) + 2\text{H}_2\text{O}(\text{l}) Ba(OH)2(aq)+2HCl(aq)→BaCl2(aq)+2H2O(l)In the titration, 15.0 cm315.0\text{ cm}^315.0 cm3 of 0.080 mol/dm30.080\text{ mol/dm}^30.080 mol/dm3 Ba(OH)2\text{Ba(OH)}_2Ba(OH)2 solution is found to react exactly with 25.0 cm325.0\text{ cm}^325.0 cm3 of the HCl\text{HCl}HCl solution.
Calculate the concentration, in mol/dm3\text{mol/dm}^3mol/dm3, of the HCl\text{HCl}HCl solution.
