Journal Entry:

What does redox stand for? What must be happening in these types of reactions?

Learning Intentions

• You will learn about solution stoichiometry and be able to convert volumes of known concentrations into unknown concentrations of substances in other parts of a chemical reaction.

• You  will understand that electrons are transferred from the substance that is oxidized to the substance that is reduced and be able to identify each.

• You will learn to determine oxidation numbers for all atoms in the reactants and products.

Closing Task:

You can solve solution stoichiometry problems using data from titrations.

You can predict oxidation numbers of all elements in a redox reactions and determine which element is being oxidized and which is being reduced.

Content Standards being covered:

Quantitative information can be derived from stoichiometric calculations that utilize the mole ratios from the balanced chemical equations. The role of stoichiometry in real world applications is important to note, so that it does not seem to be simply an exercise done only by chemists.  (EK 3.A.2) 

In oxidation-reduction (redox) reactions, there is a net transfer of electrons. The species that loses electrons is oxidized, and the species that gains electrons is reduced. (EK 3.B.3)
