10.0 g of alloy containing only Fe, Cr and Ni when heated with dil. HNO3 dissolved to give Fe3+, Cr3+ and Ni2+ respectively. The resulting solution was diluted to a total volume of 250.00 cm3 by adding distilled water. 25.00cm3 of the diluted solution was treated with excess NaOH and H2 O2 . The obtained precipitate P was fltered and yellow colour fltrate Q was acidifed with dil. H2 SO4 acid, and titrated with 1.0mol dm-3 Fe2+ solution. The volume...
