A central concept that underlies all of the reasoning we will be doing about chemical equilibrium systems is the progress of reaction. This tutorial defines and examines the progress of reaction. This tutorial discusses how to determine which concentrations appear in the law of mass action when calculating the reaction quotient Q.

This tutorial looks at the relation between the equilibrium state reached by reversible reactions and the thermodynamics of those reactions. This movie describes the hemoglobin scenario from the perspective of quantitative calculations. How do we determine final concentrations for equilibrium systems? When reactions are reversible, neither the forward nor the backward reaction will progress to completion. This page demonstrates quantitative calculations…. Many reversible reactions have large or small values for their equilibrium constant, K.

That is, one reaction either the forward or the reverse is much stronger than the other reaction. For instance, most…. A general introduction to a number of techniques used to determine how chemical reactions alter the concentrations of chemical species. Quantitative calculations on chemical equilibrium systems often lead to rather tedious algebra involving cubic or high-order polynomial equations.

Since all possible states of a chemical reaction e. This tutorial demonstrates quantitative calculations to determine final concentrations in reactions that go to completion. This tutorial describes how buffers protect against pH changes when strong acid or base is added. This set of problems and tutored examples walks students through calculating the amount weak acid and a strong base needed to create a buffer solution with a specific concentration.

This tutorial describes the calculations for determining the pH of a buffer solution. This set of problems and tutored examples walks students through calculating the pH of a buffer.

The ChemCollective is organized by a group of faculty and staff at Carnegie Mellon who are interested in using, assessing, and creating engaging online activities for chemistry education.

This interactive tutorial illustrates the steps in measuring the amount of food coloring in sports beverages to show qualitative and quantitative analysis techniques.

Sample calculations and automatically graded evaluation questions are also included. Using the Virtual Laboratory, design an experiment to quickly determine which of the two reagents, HCl or NaOH, is 10 times more concentrated than the other. In this lab, you will determine the concentration of acetic acid in vinegar using a 0.
