Curated OER
Laboratory: Hydrated Salts
In this hydrated salt worksheet, learners answer questions after completing a lab experiment using a hydrated salt. The calculate the empirical formula for the hydrate, they name the hydrate and they determine the mass of the water in...
Curated OER
Hydrated Salt
Students plan, design, and carry out an experiment to determine an empirical formula for a hydrated salt X that tell students when all the water has been removed from hydrate crystals.
Curated OER
Formula of a Hydrate Lab
In this hydrate worksheet, students find the formula of an unknown salt by determining the mass of water in the heated compound. Students burn off the water and record data to establish the final mass and formula of the hydrate.
Chymist
Hydrates
What occurs when a hydrate is heated? Lead your class in exploring the answer to this question as they investigate the properties of a hydrated compound. They heat copper(II) sulfate pentahydrate and evaporate the water byproduct to...
Curated OER
Predicting the pH of Salt Solutions
A single page provides you with lecture notes for your lesson on hydrolysis. Introduce your chemistry class to Bronsted-Lowry theory by explaining the hydrolysis of acidic cations and basic anions. Show them how the resulting pH can be...
Curated OER
Chemical Equilibrium
In this chemical equilibrium worksheet, students review hydration, dissociation, and colligative properties. Students also review Le Chatelier's principle. This worksheet has 15 short answer questions and 12 problems to solve.

Golf Ball Lab
The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...
Smithsonian Institution
Watching Crystals Grow
Amazing science can sometimes happen right before your eyes! The class gets cozy as they watch crystals grow. They use Epsom salts, rocks, and food coloring to create crystals. They'll observe the entire process, documenting every step...
