Question

4.16 (Brown/LeMay 12th Ed) Specify what ions are present upon dissolving each of the following substances in water: a) Mgl2 -> Mgta) +2I b) Al(NO3)3 -> A13++3N03 c) HCIO4 d) NaCH;COO -> Natt CH-CO0 (ai) 2, cac)

Answer 1

(a) Mg I2 - Mg2+ + 21 (b) Al (Nas) → Agst + 3103 (C) HClef + H2O = Hot +C104 (d) NaCH₃Co - Nat + CH₂ 200 Key point: The net Charge Same aceviding on both the sides of equation should be to the principle of 'electroncu rality.
