Solution

${B a B r}_{2}$ in aqueous solution gives yellow ppt with $K_{2} {C r O}_{4}$ as well as with ${A g N O}_{3}$
With $K_{2} {C r O}_{4}$ , barium bromide gives yellow ppt of barium chromate whereas with ${A g N O}_{3}$ , it gives light yellow ppt of silver bromide.
$K_{2} {C r O}_{4} + B a B r_{2} \to {C r O}_{4} ↓ (y e l l o w) + 2 K B r$
${A g N O}_{3} + B a B r_{2} \to B a N O_{3} + 2 A g B r ↓ (l i g h t y e l l o w)$
