The first and second ionization enthalpies of a metal are 496 and 4560kJ mol-1 . respectively. How many moles of HCl and H2SO4 . respectively. will be needed to react completely with 1 mole of the metal hydroxide

IE values indicate. that the metal belongs to Ist group since second IE is very high(·: only one valence electron)Metal hydroxide will be of type MOHMOH+HCl→MCl+H2O(lmol)(1mol)MOH+12H2SO4→12M2SO4+H2O(1mol)12molSo one mole of HCI required to react with one mole MOHSo 12 mole of H2SO4 required lo react with one mole MOH
