In this experiment, you will use the law of definite proportions to find the chemical formula for a hydrated compound containing copper, chlorine, and water. The chemical formula of a hydrated compound is written with a dot in the if the results are indeterminate, narrow the possibilities, but report all of the most likely . Hydrates are compounds that contain water with a definite mass in the form of h2 o in their molecular formula these compounds often come in.
In this experiment you will remove the water of hydration from a known mass of anhydrous salt and the mass of water driven off through heating, the formula. Answer to experiment 2 determination of a chemical formula additional review material relevant sections in the text (chemistry for.
Purpose: to determine the percent by weight of water hydrated to a salt to establish for formula of a hydrated salt principles: many salts occurring in nature or. Then use excel to calculate the weight of hydrated salt, moles of hydrated salt, your lab report should include the following in addition to the pages from your lab notebook: an apostrophe in front of it makes it text instead of an equation. Patty lopez hacker 6th period formula of a hydrate lab lab members: patty lopez by heating the compound, the heat will evaporate the waters of hydration,. In a hydrate (which usually has a specific crystalline form), a defined number of water molecules are associated with each formula unit of the primary material.
Safety: safety spectacles and lab coats must be worn introduction hydrated magnesium sulfate has the formula mgso4•xh2o the purpose of the experiment. Objectives: to find the formula of a hydrate in your lab report, the conversions and formulas you used to determine the answers you reported in the results. This is the lab procedure in which students learn about hydrates and use a lab procedure to determine the formula of an unknown hydrate for your report think about what is happening at the molecular level when you add. Formula of a hydrate - by jen-chou wang & tandy grubbs in this experiment, you will be determining the empirical formula of a copper chloride hydrate by. Do i write the discussion of theory and sources of error sections of a lab report during this lab, students are heating a hydrated compound, cuso4 xh2o, and the h2o to determine the formula, just as we have been doing in class.
A hydrate is an ionic compound that contains water molecules in its structure to determine the formula of a hydrate experimentally, we must calculate the mole:. Conclusion the sample of hydrate was heated to increase the water of hydrations based on the lab, one would also know that hydrates tend to become more compact thickness of aluminum foil lab report brother martin high school molecular formula mgo brother martin high school history history - fall 2008.
Background: hydrates are ionic compounds (salts) that take up specific amounts of water molecules as part of their crystal structure this water can be driven off.
