Question

Which of the following acid radical will not produce a precipitate with $AgN{O}_3$ solution?

• A. $F^{-}$
• B. $B{r}^{-}$
• C. $C{O}_3^{2-}$
• D. $P{O}_4^{3-}$

Answer 1

Answer: (A)

With $F^{-}$ , no precipitate is obtained because of low lattice energy of $AgF$ , so it remains in ionized state.
