Question

For the following 6 equations what is the complete equation, name of producs, full ionic equation, and the net ionic equation? 1. NaOH + HCl 2. KOH + HCl 3. AgNO₃ + KCl 4. BaCl₂ + Na₂SO₄ 5. Na₂CO₃ + CaCl₂ 6. Zn + HCl

Answer 1

Ionic equation includes all the ions in the reaction. Net ionic equation includes only those ions which undergo chemical reaction. Spectator ions are omitted in net ionic equation.

1

NaOH reacts with HCl to form sodium chloride (NaCl). Total ionic equation is written as follows:

Na⁺ (aq) + OH^- (aq) +   H⁺ (aq) + Cl^- (aq)    ----> Na⁺ (aq) +   Cl^- (aq) + H₂O(l)

In this equation Na⁺, Cl^- ions do not undergo change and acts as spectator ions. In net ionic equation these spectator ions are excluded. Net ionic equation is written as follows:

OH^- (aq) + H⁺ (aq)   ----> H₂O (l)

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

2

KOH reacts with HCl to form potassium chloride (KCl). Total ionic equation is written as follows:

K⁺ (aq) + OH^- (aq) +   H⁺ (aq) + Cl^- (aq)     -----> K⁺ (aq) +   Cl^- (aq) + H₂O(l)

In this equation K⁺, Cl^- ions do not undergo change and acts as spectator ions. In net ionic equation these spectator ions are excluded. Net ionic equation is written as follows:

OH^- (aq) + H⁺ (aq)   ----> H₂O (l)

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

3

AgNO₃ reacts with KCl to form Silver chloride (AgCl). Total ionic equation can be written as follows:

Ag⁺ (aq) + NO₃^- (aq) +   K⁺ (aq) + Cl^- (aq)     ----> K⁺ (aq) +   NO₃^- (aq) + AgCl (S)

In this equation K⁺, NO₃^- ions do not undergo change and acts as spectator ions. In net ionic equation these spectator ions are excluded. Net ionic equation is written as follows:

Ag⁺ (aq) + Cl^- (aq)   ----> AgCl (S)

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

4

BaCl₂ reacts with Na₂SO₄ to form a precipitate of barium sulfate (Ba(SO₄)₂). Total ionic equation can be written as follows:

Ba²⁺ (aq) + 2Cl^- (aq) +   2Na⁺ (aq) + SO₄^2- (aq)     ----> 2Na⁺ (aq) +   2Cl^- (aq) +   BaSO₄ (S)

In this equation Na⁺, Cl^- ions do not undergo change and acts as spectator ions. In net ionic equation these spectator ions are excluded. Net ionic equation is written as follows:

Ba²⁺ (aq) + SO₄^2- (aq)   ---->   BaSO₄ (S)

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

5

Na₂CO₃ reacts with CaCl₂ to form a precipitate of calcium carbonate (CaCO₃). Total ionic equation is written as follows:

2Na⁺ (aq) + CO₃^2- (aq) +   Ca²⁺ (aq) + 2Cl^1- (aq)     ----> 2Na⁺ (aq) +   2Cl^- (aq) +   CaCO₃ (S)

In this equation Na⁺, Cl^- ions do not undergo change and acts as spectator ions. In net ionic equation these spectator ions are excluded. Net ionic equation is written as follows:

Ca²⁺ (aq) + CO₃^2- (aq)   ---->   CaCO₃ (S)

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

6

Zn reacts with HCl to form a precipitate of zinc chloride (ZnCl₂). Total ionic equation is written as follows:

Zn (s) + 2H⁺ (aq) + 2Cl^- (aq)     ----> Zn²⁺ (aq) +   2Cl^- (aq) +   H₂ (g)

In this equation Cl^- ions do not undergo change and acts as spectator ions. In net ionic equation these spectator ions are excluded. Net ionic equation is written as follows:

Zn (s) + 2H⁺ (aq)     ----> Zn²⁺ (aq) +   H₂ (g)
