Which of the following is the net ionic equation for the reaction that occurs during the titration of nitrous acid with potassium hydroxide? A) HNO₂ + KOH → K⁺ + NO₂^- + H₂O B) H⁺ + OH^- → H₂O C) HNO₂ + OH^- → NO₂^- + H₂O D) HNO₂ + H₂O → NO₂^- + H₃O⁺ E) HNO₂ + K⁺ + OH^- → KNO₂ + H₂O

Question

Quizplus · Accepted Answer

In the reaction between nitrous acid (HNO₂) and potassium hydroxide (OH^-), they react to form potassium nitrite (KNO₂) and water (H₂O). The net ionic equation only includes the species that participate in the reaction, which in this case are the nitrous acid and hydroxide ions. Therefore, the net ionic equation is HNO₂ + OH^- → NO₂^- + H₂O. Choice C is the only option that includes this net ionic equation.
