Question

0.200 M KOH is used to titrate 50.0 mL samples of 0.200 M HNO₃ and 0.200 M HNO₂, individually. Match them to their corresponding titration curve.

Titration curve A showing pH change for HNO3 with KOH. Titration curve B showing pH change for HNO2 with KOH.

Accepted Answer

Titration curve A corresponds to the titration of HNO₃ with KOH, while titration curve B corresponds to the titration of HNO₂ with KOH.

Answer

Titration curve A corresponds to the titration of HNO₂ with KOH, while titration curve B corresponds to the titration of HNO₃ with KOH.
