The concentration of sulfate in a solution containing a mixture of sulfuric acid is to be determined. A 25.0 mL portion of the sample is treated with 10.00 mL of 0.0500 M BaCl₂. The resulting precipitate is filtered off and the supernatant solution containing the Ba²⁺ is then titrated with 0.0354 M EDTA which gives an end point at 7.45 mL. (a) Identify the type of EDTA titration method used. (b) Calculate the molar concentration of sulfate in the sample
