Question
**Participation** Decide whether aqueous solutions are acidic, basic or neutral. - KCl - NaF - Zn(NO₃)₂ - NH₄NO₃ - KNO₃ - Al(NO₃)₃ - Zn(HCOO)₂ Constants: - \( K_a \) for \( \text{Zn(H}_2\text{O)}_6^{2+} = 1 \times 10^{-9} \) - \( K_b \) for \( \text{HCOO}^- = 5.6 \times 10^{-11} \) --- This activity involves determining the acidic, basic, or neutral nature of various aqueous solutions by considering the given dissociation constants.
