Question

Write down the net ionic equation, Include phases, for the reaction of AgNO3(aq) with K2SO4(aq).Refer to the solubility rules as necessary.

Answer 1

The net ionic equation is: 2Ag⁺ (aq) + SO₄²⁻ (aq) ⇒ Ag₂SO₄ (s)

Step-by-step explanation:

The balanced reaction is:

2 AgNO₃ (aq) + K₂SO₄ (aq) ⇒ Ag₂SO₄ (s) + 2 KNO₃ (aq)

The ionic equation is:

2 Ag⁺(aq)+2 NO₃⁻ (aq)+2 K⁺ (aq)+SO₄²⁻ (aq) ⇒ Ag₂SO₄ (s)+2 K⁺(aq)+2 NO₃⁻ (aq)

We identify the spectator ions (they are underlined):

2 Ag⁺ (aq)+2 NO₃⁻ (aq)+2 K⁺ (aq)+SO₄²⁻ (aq) ⇒ Ag₂SO₄ (s)+2 K⁺(aq)+2 NO₃⁻ (aq)

Finally, we remove them from the equation:

2 Ag⁺ (aq) + SO₄²⁻ (aq) ⇒ Ag₂SO₄ (s)

All nitrates are soluble. All sulfates are soluble, with the exception of CaSO₄, SrSO₄, BaSO₄, PbSO₄, HgSO₄, Hg₂SO₄ and Ag₂SO₄.
