A liquid (X) having a molecular formula C_(6) H_(12) O_(2) is hydrolysed with water in the presence of an acid to give a carboxylic acid (Y) and an alcohol (Z) . Oxidation of (Z) with chrome acid gives (Y) . What are the structures of (X), (Y) , and (Z) ?

In a chrome plating plant, CrO_4^(2-) (chromate) ions are present in waste water. The chromate ions are reduced to insoluble chromium hydroxide, Cr(OH)_3 , by dithionate ion, S_2O_4^(2-) in basic medium. CrO_4^(2-)+S_2O_4^(2-)+overset(ɵ)(O)H+H_2OtoCr_2(OH_3)+SO_3^(2-) 10 L of water requires 522 g of Na_2S+2O_4 . Calculate the normality and molarity of CrO_4^(2-) in waste water. Also express the concentration of Na_2CrO_4 in ppm.
