One litre of a mixture containing BaF_(2) and H_(2)SO_(4) was taken for analysis. 25 mL of this mixture was added to 100 mL of 0.05 N K_(2)CO_(3) solution and precipitate was filtered off. The filtrate required 12 mL fo 0.025 M oxalic acid solution using phenolphthalein as indicator. Find the strength of BaF_(2) and H_(2)SO_(4) in mixture.
