Verified step by step guidance1
Identify the type of reaction: The given reaction involves an acid (HNO2) and water, suggesting an acid-base reaction.
Determine the acid and base: HNO2 is a weak acid, and H2O can act as a base in this context.
Predict the products: In an acid-base reaction, the acid donates a proton (H+) to the base. HNO2 will donate a proton to H2O, forming NO2- and H3O+.
Write the balanced chemical equation: HNO2 + H2O ⇌ NO2- + H3O+.
Verify the charge and mass balance: Ensure that the number of atoms and the total charge are the same on both sides of the equation.
