Ram prepared an aqueous solution of `CuSO_(4)` in beaker`X``&` an aqueous solution of `FeSO_(4)` in beaker Y. Then he dropped some iron pieces in beaker X `&` some zinc pieces in beaker `Y` .After about`10` hours,he observed that the solutions in `X` and `Y` respectively appear-

Freezing point of a 4% aqueous solution of X is equal to freezing point of 12% aqueous solution of Y .If molecular weight of X is A then molecular weight of Y is :

Nature of aqueous solutions of two different amino acids X and Y are acidic and basic. Now X and Y are.

Freezing point of a 4% aqueous solution of X is equal to freezing point of 12% aqueous is reaction of Y .if molecular weight of X is A then molecular weight of Y is :

The coordinates of points in the table represent some of the solutions of the equation x-y+2=0.

A piece of ice is floating in a beaker containing thick sugar solution of water. As the ice melts, the total level of he liquid

If x = a and y = b is the solution of the equations x - y =2 and x + y = 4 , then the values of a and b are, respectively

If x = a and y = b is the solution of the equations x - y =2 and x + y = 4 , then the values of a and b are, respectively

p-Amino-N,N-dimethylaniline is added to a strongly acidic solution of X. The resulting solution is treated with a few drops of aqueous solution of Y to yield blue colouration due to the formation of methylene blue. Treatment of aqueous solution of Y with reagent potassium hexacyanoferrate (II) leads to the formation of an intense blue precipitate. The precipitate dissolves on excess addition of the reagent. Similarly, the treatment of the solution of Y with the solution of potassium hexacyanoferrate (III) leads to a brown colouration due to the formation of Z. Q. Compound X is
