Chem Collective: Determining the Concentration of an Unknown Solution

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

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.

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 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...
