Question:medium
K\(_2\)Cr\(_2\)O\(_7\) on heating with aqueous caustic soda gives
K\(_2\)Cr\(_2\)O\(_7\) on heating with aqueous caustic soda gives
Show Hint
The equilibrium: Cr\(_2\)O\(_7^{2-}\) (orange) + H\(_2\)O \(\rightleftharpoons\) 2CrO\(_4^{2-}\) (yellow) + 2H\(^+\). In acidic medium, dichromate is favored; in basic medium, chromate is favored.
