Determination of the Percent Hydration and the Simplest Formula of a Hydrate
Does the crystal structure of a hydrated solid determine the proportion of water absorbed, or does the application of heat change the absorption? Scholars experiment with both variables to determine the answer. They add their collected...
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
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.
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
