CHE 201 Lecture Notes - Lecture 9: Molar Concentration, Redox, Stoichiometry
Document Summary
Molarity (m), moles of solute (mol), volume of solution (l) Dilution is the process of preparing a less concentrated solution from a more concentrated one. The concentration of a solution is the amount of solute dissolved in a given quantity of solvent or solution, one of the factors that can influence reactions in aqueous solutions. Molarity or molar concentration (m) is defined as the number of moles of solute per liter of solution millimoles (mmol) Square brackets around a chemical species can be read as the concentration of that species. A redox reaction is one in which there are changes in oxidation states. This reaction takes place in aqueous solution, so we can add h2o as needed to balance the equation. This particular reaction takes place in acidic solution, so we can add h+ as needed to balance the equation (some reactions take place in a basic solution, enabling us to add oh- as needed for balancing.
