A mixture of salts was treated to determine the barium constent. A 0.230 g sample was dissolved and treated with excess potassium chromate. The precipitate of BaCrO_(4) was dissolved in dil HCl to convert BaCrO_(4) to Cr_(2)O_(7)^(2-) anion. The solution treated with excess sodium iodide and trilodide produced was titrated with 21 mL of 0.095 M sodium thiosulphate. Calculate the % of BaCl_(2). 2H_(2)O in the sample. [Given Molar mass of BaCl_(2.2H2O)=244]
