Chem Collective: Determining the P Ka and Concentration Ratio

In this limiting reagents problem, students are asked to determine the amount of silver nitrate dissolved in a solution by performing a reaction with solid NaCl. In this randomized activity, each student is given a different unknown...

Using the Virtual Laboratory design, students perform an experiment to determine the concentration of the unknown HCl solution to four significant figures.

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.

A virtual lab where students determine the concentration of acetic acid in vinegar using a 0.110 M NaOH standard solution and an acid-base indicator, phenolphthalein.

Perform a titration experiment to determine the concentration of absorbic acid in one medium peach.

Perform a titration using an indicator to determine the concentration of an HCl solution.

In this limiting reagents problem, students are given specific concentrations of DNA solutions and are asked to predict what products and reactants will remain after a specific volumes are mixed and reaction has occurred.

Students use the virtual lab to determine how four unknown substances react with each other including their stoichiometric coefficients. In this randomized activity, each student receives a different reaction and students can check their...
