Curated OER
pH Lab
For this pH worksheet, young scholars experiment with dilutions of acidic solutions to test for the pH using cabbage as an indicator. They then test a variety of substances for pH. On day two of the lab, they test conductivity of...
Curated OER
Additional Aqueous Solution Review Problems
In this solutions instructional activity, students balance chemical equations, classify reactions by the type of reaction it represents, and review the solubility rules. Students practice working out double displacement, neutralization,...
Curated OER
Parts-Per-Million Concentration Lab
Students develop a comprehension of parts per million as a concept. They work in teams to create successive dilutions of a solution to reach a parts-per-million concentration. Students list what they think the atmosphere is made of. They...

Chem Collective: Glucose Dilution Problem
In this activity, students use the virtual lab to create a 0.025M glucose solution from a standard 1M glucose solution. First, they calculate the correct volumes of 1M glucose solution and water to mix together to create the final 0.025M...

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...
