Chem Collective: Determining Reactants and Products in a Solution of Dna

Determine the solubility product constatnt (Ksp) for various solids with this virtual lab.

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.

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

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...

In this advanced limiting reagent problem, students use the virtual lab to determine the concentration of a solution of DNA by reacting it with known amounts of a fluorescent dye which binds to the DNA.

In this activity, students practice with experiments involving limiting reagents and the test their knowledge to determine the concentration of an unknown solution.

In this problem, students determine the limiting reagent in a reaction involving the remediation of arsenic from drinking water.

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.
