Identifying Anions in Solution (HSC SSCE Chemistry): Flashcards

White, pale cream, pale yellow

Dilute $\text{NH}_3$, conc. $\text{NH}_3$, insoluble

Prevent false positives from $\text{CO}_3^{2-}$ & $\text{PO}_4^{3-}$

Bubbles of $\text{CO}_2$ gas produced

$\text{SO}_4^{2-}$: any pH; $\text{PO}_4^{3-}$: pH > 6 only

Ammonium molybdate in $\text{HNO}_3$

$\text{OH}^-$, $\text{CO}_3^{2-}$, $\text{CH}_3\text{COO}^-$

$[\text{Ag}(\text{NH}_3)_2]^+$ (diamminesilver(I))

Limewater turns milky

Reddish brown solution; disappears with $\text{HCl}$
