What is the purpose of the water of hydration lab?
The goal of the experiment is to determine the number of moles of water per mole of the anhydrous compound in the given unknown. The experimental design is based on the fact that heating the hydrated compound can eliminate the waters of hydration.
How do you calculate water of hydration?
Divide the mass of the water lost by the mass of hydrate and multiply by 100. The theoretical (actual) percent hydration (percent water) can be calculated from the formula of the hydrate by dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and multiplying by 100.
What was the experimental of water in the hydrate?
EXPERIMENTAL MEASUREMENT OF PERCENT HYDRATION: The difference between the two masses is the mass of water lost. Dividing the mass of the water lost by the original mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.
What is meant by the water of hydration?
Definition of water of hydration : water that is chemically combined with a substance to form a hydrate and can be expelled (as by heating) without essentially altering the composition of the substance.
What is correct about the hydrate?
hydrate, any compound containing water in the form of H2O molecules, usually, but not always, with a definite content of water by weight. The best-known hydrates are crystalline solids that lose their fundamental structures upon removal of the bound water.
What is hydrated water?
: water that is chemically combined with a substance to form a hydrate and can be expelled (as by heating) without essentially altering the composition of the substance.
What was the initial mass of the hydrate in the hydrate lab?
The initial mass of the hydrated salt was 0.807 g. The student heated the crucible for 10 minutes with the cover slightly ajar. After cooling, the dried salt weighed 0.735 g.
What is the mass of water in the hydrate?
The mass of water in the hydrate is the coefficient (6) multiplied by the molar mass of H2O. The molar mass of the hydrate is the molar mass of the CoCl2 plus the mass of water.

Which of the following is the best definition for waters of hydration?
noun Chemistry. the portion of a hydrate that is represented as, or can be expelled as, water: now usually regarded as being in true molecular combination with the other atoms of the compound, and not existing in the compound as water.
