WebAn aqueous solution of hydrochloric acid contains 36% HCl by mass. (a) calulate the mole fraction of HCl in the solution. (b) calculate the molality of HCl in the solution. (a) moles of HCl = .99 mol HCl moles of H20 = 3.6 mol H2O XHCl = .99/ (3.6+.99) = .22 (b) molality of HCl = .99 mol HCl/.064 kg H2O = 15m WebBefore the equivalence point, HCl is present in excess and the pH is determined by the concentration of unreacted HCl. At the start of the titration the solution is 0.100 M in HCl, which, because HCl is a strong …
