CrO_(4)^(2-) (yellow) changes to Cr_(2)O_(7)^(2-) (orange) in pH=x and vice-versa in pH=y. Hence, x and y are:

When ferrous oxalate is titrated against K_(2)Cr_(2)O_(7) , milli equivalents of Fe^(2+),C_(2)O_(4)^(2-)andCr_(2)O_(7) in the redox reaction are X,Y and Z respectively , then :-

Assertion : In acidic medium, K_2Cr_2O_7 exists as Cr_2O_7^(2-) (orange) while in basic medium it is converted to CrO_4^(2-) (yellow). Reason : K_2Cr_2O_7 is hygroscopic in nature and changes colour on reaction with water.
