Question

Write the molecular equation for the reaction that occurs, if any, when solutions of the following substances are mixed: nitric acid and potassium carbonate. Make sure that you have properly identified all of the phases in your answer.

Answer 1

The balanced molecular equation for the reaction is:

`2HNO_{3_((aq)) }` +
`K_(2) CO_(3) _((s))` →
`2KNO_(3) _((s))` +
`H_(2) O_{(l)` +
`CO_(2) _((g))`↑

Step-by-step explanation:

The weak nitric acid reacts with the strong potassium base to produce salt, water and carbon dioxide which is given off.

Molecular ratio of reactants is 2 : 1.

All phases are represented in the equation: aq for aqueous, l for liquid and g for gas (notice how they are written in subscript).
