Mass Changes in Chemical Reactions—Microscale Chemistry
What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Dartmouth College: Chem Lab: Calorimetry 1 Enthalpy of Formation of Mg O
In this lab experiment students are asked to determine the standard molar enthalpy of formation of magnesium oxide, MgO. Students are asked to use Hess's Law and the enthalpy changes of several other solution reactions during this...
University of Colorado
University of Colorado: Ph Et Interactive Simulations: Beer's Law Lab
An interactive simulation that teaches about Beer's Law, solutions, concentration, spectrophotometry, and more through observations to explore how much light is absorbed and transmitted with changes in thickness and color. This...

Chem Collective: Acid Dilution Problem
In this activity, students use the virtual lab to create 500mL of 3M HCl solution from a concentrated stock solution of 11.6M HCl. They must first calculate the correct volumes of 11.6M HCl solution and water to mix together to create...

Chem Collective: Determination of the P H Scale
This virtual lab activity where students perform the method of successive dilutions using HCl, NaOH, a pH meter, and universal indicator solution to help understand the logarithmic nature of the pH scale.
Texas Instruments
Texas Instruments: Molar Gas Lab
Students use stoichiometry to determine the mass of oxygen gas in a bottle. They may also check their answer against the amount of potassium chloride produced during the reaction.
