#### Answer

a) $BaSO_{3}$ - Barium sulfite b) $NaNO_{2}$ - Sodium nitrite c) $KMnO_{4}$ - Potassium permanganate d) $K_{2}Cr_{2}O_{7}$ - Potassium dichromate

#### Work Step by Step

a) Barium ($Ba^{2+}$) + Sulfite ($SO_{3}^{2-}$) $\longrightarrow$ $BaSO_{3}$ b) Sodium($Na^{+}$) + Nitrite ($NO_{3}^{-}$) $\longrightarrow$ $NaNO_{2}$ c) Potassium ($K^{+}$) + Permanganate ($MnO_{4}^{-}$) $\longrightarrow$ $KMnO_{4}$ d) Potassium ($K^{+}$) + Dichromate($Cr_{2}O_{7}^{2-}$) $\longrightarrow$ $K_{2}Cr_{2}O_{7}$
