Answer 1

From the chemical equation, 3 mol of Nooth is needed to precipitate 1 mol of Al Iz as Al(OH)3 Volume of a & concentration of Alla solution is 140 mL & 0.745 M. So number of moles of AlIz in the solution = (140x0.745) x1013 meter = 0.1043 moles. Concentration of Nadh solution = 0.671m So volume of Noot required = 0.1043x3 043 x3 x 103 wh 3 0.671 710 = 466.32 mb 1466.32/ h Naola
