$X = Na_2CrO_4, Y = Na_2Cr_2O_7$

(C) The reactions represent the interconversion between sodium chromate and sodium dichromate.$1$. In the first reaction: $2Na_2CrO_4 + 2H^{+} \rightarrow Na_2Cr_2O_7 + 2Na^{+} + H_2O$. Here,$X = Na_2CrO_4$ and $Y = Na_2Cr_2O_7$.$2$. In the second reaction: $Na_2Cr_2O_7 + 2KCl \rightarrow K_2Cr_2O_7 + 2NaCl$. This confirms $Y = Na_2Cr_2O_7$.Therefore,$X = Na_2CrO_4$ and $Y = Na_2Cr_2O_7$.
