$6\mathrm{.}3017$ sample was weighted Analytically and made up volumetrically to $500mL.$ A $25mL$ alliquut of this solution required a total valume of $41\mathrm{.}32mL$ of $0\mathrm{.}0987MHCl$ to reach brumocresol green endpoint Another $25mL$ alliqout of this solution was treated with $25mL$ of $0\mathrm{.}1014M$ NaOH react with excess of $BaC{l}_2$ solution und left over NaoH required $21\mathrm{.}83mL$ of $0\mathrm{.}0987MHCl$ to reach the phenolpthelin end point.
