A 25.00 ml of Ni2* solution was diluted in HCI and treated with 25.00 ml of 0.05283 M NazEDTA. The solution was neutralized with NaOH followed by addition of acetate buffer unti the pH 5.5. The solution turns yellow after addition of few drops of xylenol orange indicator Back titration using standard 0.022 MZn2 at pH 5.5 requires 17.61 ml until end point, or which the solution will turn red. Calculate for the molarity of the unknown. Ans. 0.03664 M
