Write a net ionic equation for the reaction that occurs when excess nitric acid (aq) and sodium sulfite (aq) are combined. Note: Sulfites follow the same solubility trends as sulfates.

Respuesta :

[tex]2HNO_3 + Na_2SO_4[/tex] ⇒ [tex]2NaNO_3 + H_2SO_4[/tex]

Explanation:

Reactants  -

Nitric Acid [tex](HNO_3)[/tex]

Sodium Sulfate [tex](Na_2SO_4)[/tex]

Products  -

Sulfuric Acid [tex](H_2SO_4)[/tex]

Sodium Nitrate [tex](NaNO_3)[/tex]

The reaction is as follows -

Nitric Acid + Sodium Sulfate ⇒ Sodium Nitrate + Sulfuric Acid

[tex]HNO_3 + Na_2SO_4[/tex][tex]NaNO_3 + H_2SO_4[/tex]

To balance the above equation we need to add a coefficient of 2 in front of nitric acid on the right-hand- side and a coefficient of 2 in front of sodium nitrate on the left-hand-side.

∴ The balanced equation is as follows -

[tex]2HNO_3 + Na_2SO_4[/tex] ⇒ [tex]2NaNO_3 + H_2SO_4[/tex]
