Curated OER
What Happens When Chemical Are Put Together?
In this chemical reactions worksheet, learners answer 20 multiple choice questions about chemical equations, chemical formulas, oxidation and reduction reactions and acids, bases and salts.
Curated OER
Where in the World is Carbon Dixoide?
Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...
Curated OER
Vitamins
Students determine the amount of vitamin C present in 3 samples of juice stored in various light conditions. In this vitamin lesson plan, students investigate the amount of vitamin C present in juice exposed to different quantities of...
Curated OER
Solutions and Solubility Review
In this solutions and solubility review worksheet, students are given main ideas about intermolecular forces, concentrations of solutions, molar solutions, ionic equations, solubility rules, acids and bases and titrations. Students...

Chem Collective: Standardization of Na Oh With a Khp Solution: Acid Base Titration
Use the Virtual Laboratory to standardize an unknown NaOH solution (approximately 0.2M) to four significant figures via titration with 25.00 mL of a KHP standard solution.
Dartmouth College
Dartmouth College: Acids, Bases, and Buffers 1: Monoprotic and Polyprotic Acids
In this experiment, you will explore the behavior of the monoprotic acid (acetic acid) and the polyprotic acid (phosphoric acid). By titrating, you will examine the acid and conjugate base species present across the pH scale and the...

Serc: Acid Base Titration of an Eggshell
In this lab, students are scientists from the Department of Agriculture and presented with the problem that a farmer has brought to them. The farmer believes the problems are due to illegal dumping of PCB's and other chemicals that...
Dartmouth College
Dartmouth College: Chem Lab: Coordination Chemistry 3.1: Acid/base Analysis
In this experiment, you will examine the acidity of your coordination complex's water ligand. You will determine the acid dissociation constant of the complex by titrating it with a base. There are eight weeks of experiments in this series.

Chem Collective: Determine the Concentration of the Unknown Strong Acid
Perform a titration using an indicator to determine the concentration of an HCl solution.
Chemistry Collective
Chem Collective: Determining the Concentration of an Unknown Solution
Using the Virtual Laboratory design, students perform an experiment to determine the concentration of the unknown HCl solution to four significant figures.
Chemistry Collective
Chem Collective: Determining Reagent Concentrations
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.
