Question

2) Rewrite the net ionic reaction on the page below. Example: Notebook Rxn: (AgNO, + NaCl): Total: Ag" (aq) + NO: (aq) + Na" (aq) + Cl(aq) → AgCl(s) + Na'(aq) + NO, (aq) Net: Ag" (aq) + Cl(aq) → AgCl(s) Page below Rxn: (AgNO, + NaCl): Ag*(aq) + Cl(aq) → AgCl(s) 3) If there is NO reaction, simply write NR. Rxn IA (CuSO. + KI): Rxn IB (AICI, + KI): Rxn IC (Zn(C,H,O2)2 + KI): Rxn ID (Pb(NO3)2 + KI): Rxn IE (Na3PO, + KI): Rxn IF (NaOH + KI):

Please write the net ionic reaction only for every reaction and complete every box. If there is no reaction, please write NR. Thank you.

Answer 1

3.Ans :- Rxn IA

Molecular equation is :

CuSO₄ (aq) + 2KI (aq) -------------------> CuI₂ (s) + K₂SO₄ (aq)

Completely dissociate the strong electrolytes like CuSO₄, KI and K₂SO₄. While don not ionize the weak electrolytes like CuI₂ .

Therefore,

Total ionic equation is :

Cu²⁺ (aq) + SO₄^2- (aq) + 2K⁺ (aq) + 2I^- (aq) -------------------> CuI₂ (s) + 2K⁺ (aq) + SO₄^2- (aq)

Cancel the spectator ions like K⁺ and SO₄^2- on both the side :

Net ionic equation is :

Cu²⁺ (aq) + 2I^- (aq) -------------------> CuI₂ (s)

------------------------------------------------------------------------------------

Rxn​​​​​​​ IB

Molecular equation is :

AlCl₃ (aq) + 3KI (aq) -------------------> AII₃ (aq) + 3KCl (aq)

Completely dissociate the strong electrolytes like AlCl₃ , KI, AII₃ and KCl.

Therefore,

Total ionic equation is :

Al³⁺ (aq) + 3Cl^- (aq) + 3K⁺ (aq) + 3I^- (aq) -------------------> Al³⁺ (aq) + 3I^-​​​​​​​ (aq) + 3K⁺ (aq) + 3Cl^- (aq)

Cancel the spectator ions like K⁺, I^- and Cl^- on both the side :

So,

Net ionic equation is :

NR

------------------------------------------------------------------------------------

Rxn​​​​​​​ IC

Molecular equation is :

Zn(C₂H₃O₂)₂ (aq) + 2KI (aq) -------------------> ZnI₂ (aq) + KC₂H₃O₂(aq)

Completely dissociate the strong electrolytes like Zn(C₂H₃O₂)₂ , KI, ZnI₂ and KC₂H₃O₂.

Therefore,

Total ionic equation is :

Zn²⁺ (aq) + 2C₂H₃O₂^- (aq) + 2K⁺ (aq) + 2I^- (aq) -------------------> Zn²⁺ (aq) + 2I^-​​​​​​​ (aq) + 2K⁺ (aq) + 2C₂H₃O₂^- (aq)

Cancel the spectator ions like K⁺, C₂H₃O₂^- ,Zn²⁺  and l^- on both the side :

So,

Net ionic equation is :

NR

------------------------------------------------------------------------------------

Rxn​​​​​​​ ID

Molecular equation is :

Pb(NO₃)₂ (aq) + 2KI (aq) -------------------> PbI₂ (s) + 2KNO₃ (aq)

Completely dissociate the strong electrolytes like Pb(NO₃)₂, KI and KNO₃ . While do not ionize the weal electrolytes like PbI₂.

Therefore,

Total ionic equation is :

Pb²⁺ (aq) + 2NO₃^- (aq) + 2K⁺ (aq) + 2I^- (aq) -------------------> PbI₂ (s) + 2K⁺ (aq) + 2NO₃^- (aq)

Cancel the spectator ions like K⁺ and NO₃^- on both the side :

So,

Net ionic equation is :

Pb²⁺ (aq) + 2I^- (aq) -------------------> PbI₂ (s)
