Assertion (A): Potassium dichromate is preferred to Na_(2)Cr_(2)O_(7) for use in volumetric analysis (titrations) Reason (R): Na_(2)Cr_(2)O_(7) is hygroscopic whilst the K_(2)Cr_(2)O_(7) is not Which of the following is correct ?

Which of the following produce Cr_(2)O_(3) along with O_(2) ?

Potassium dichromate (K_(2)Cr_(2)O_(7)) is an orange coloured compound , very frequently used in laboratory as an oxidising agent as well as in a redox titration. It is generally prepared from chromite (FeCr_(2)O_(4)) ore according to the following reactions: (1) Fusion of chromite ore with sodium carbonate in excess of air. FeCr_(2)O_(4) + Na_(2)CO_(3) + O_(2) rarr Na_(2)CrO_(4)+Fe_(2)O_(3) +CO_(2) (2) Acidifing filtered sodium chromate solution with sulphuric acid. Na_(2)CrO_(4) + H_(2)SO_(4) rarr Na_(2)Cr_(2)O_(7) + Na_(2)SO_(4) + H_(2)O (3) Treating sodium dichormate with potassium choride . Na_(2)Cr_(2)O_(7) + KCl rarr K_(2)Cr_(2)O_(7) + NaCl If whole of the chormite ore given in the previous question gets consumed and sufficient amount of rest of the reactants are given, then the mass of K_(2)Cr_(2)O_(7) obtained is:
