The mass percent of sulfuric acid H 2 SO 4 in the given sample of battery acid needs to be deduced from its titration with Ba(OH) 2 . Concept introduction: Titration is a method of quantitative analysis which is used to determine the concentration of unknown solutions. A titrant of known concentration is added to an analyte of known volume in the presence of a suitable indicator until the equivalence point is reached which is indicated by a change in the color of the analyte. In a titration, equivalence point is the point at which the amount of titrant added is just sufficient to neutralize the amount of analyte taken. Concentration of a solution is expressed in terms of molarity which is the ratio of the moles of solute divided by the volume of the solution in liters. Molarity = Moles of solute Volume of solution (liters) − − − − ( 1 )
