# Understanding Oxidation and Reduction in Chemical Reactions### I. What is Oxidation? What is Reduction?- **Oxidation** is a chemical process where a substance loses electrons, increasing its oxidation state.- **Reduction** is the opposite process, where a substance gains electrons, decreasing its oxidation state.### II. Identifying Oxidation States in a ReactionConsider the following chemical reaction:\[ \text{Cu}^{2+} (aq) + \text{Zn} (s) \rightarrow \text{Cu} (s) + \text{Zn}^{2+} (aq) \]- **Copper (Cu) oxidation states:** - \(\text{Cu}^{2+} (aq)\): +2 - \(\text{Cu} (s)\): 0- **Zinc (Zn) oxidation states:** - \(\text{Zn} (s)\): 0 - \(\text{Zn}^{2+} (aq)\): +2### III. Identifying Oxidized and Reduced Substances- **Oxidation:** - Zinc (\(\text{Zn} (s)\)) is oxidized as it loses two electrons, resulting in \(\text{Zn}^{2+} (aq)\).- **Reduction:** - Copper ion (\(\text{Cu}^{2+} (aq)\)) is reduced as it gains two electrons, forming metallic copper (\(\text{Cu} (s)\)).Through this reaction example, you can observe how oxidation and reduction occur simultaneously, known as a redox reaction.

Given is redox reaction. Oxidation is process in which loss of electrons occurs. In this oxidation state increases. Reduction is process in which gain of electron occurs. In this oxidation state decreases. In given reaction, oxidation state are, Species oxidation states Cu2+ +2 Zn 0 Cu 0 Zn2+ +2Here , Zn(s) is oxidized and Cu2+ is reduced.

One way to determine the hardness of a water sample is to precipitate the calcium out of solution as a carbonate.
