Interpretation Introduction

Interpretation - Here, it is given that ascorbic acid protects the stomach from the carcinogenic effect of NO₂- ions by converting the ions to NO. We are asked to whether the nitrite ion is oxidized or reduced and whether ascorbic acid act as an oxidizing agent or a reducing agent.

Concept Introduction - Redox are a type of chemical reaction in which the oxidative states of the atoms are altered. These types of reactions involve both the oxidation and reduction processes; the two main concepts involved in the transfer of electrons. The chemical moiety from which the electron is removed is said to have been oxidized while the moiety which gets the electron is said to have been reduced.
