Curated OER
Laboratory: Hydrated Salts
In this hydrated salt worksheet, students 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.
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...

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...
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...
