Answer #1

(a) Reaction in Beaker A: Pb(NO3)2 (aq) + 2 NaCl (aq) = PbCl2 (s) + 2 NaNO3 (aq)

Reaction in beaker B: FeSO4 (aq) + Mg(NO3)2 (aq) = MgSO4 (s) + Fe(NO3)2 (aq)

(b) Product in beaker A: Lead chloride, Physical state: solid

Product in beaker B: magnesium sulphate, Physical state: solid

(c) Both the reactions are precipitation and double displacement reaction

(d)

+ → Nat N93003 ND lead(II) nitrate(ag) sodium chloride (aq)

(e) Spectator ions are Na+ and NO3- . Physica state: Aqueous

(f) Net ionic equation: Pb+2 (aq) + 2 Cl- (aq) = PbCl2 (s)
