Formula of a Hydrate Chemistry 11 3/5/2013 Purpose: To determine the percent by mass of water in a hydrate of copper (II) sulfate hydrate. Hypothesis: I hypothesize that when the solution is heated the hydrate will convert to an anhydrous ionic compound. Then the percentage composition will be determined by weighing the mass of the white crystals. Materials: 400ml beaker‚ hot plate‚ tongs‚ scoopula‚ electronic balance‚ glass rod‚ hot pad‚ and 4g of hydrated copper (II) sulfate Procedure:

Lisa Margonelli examines what methane hydrates are‚ the capabilities of methane hydrates‚ and the potentially detrimental affects methane hydrates can have on global warming. Methane hydrates exist in the seabed along coastlines around the world and are massive deposits of gas that are trapped in large‚ icy structures underneath the coastal sea floor. Despite inadequate funding‚ scientists around the world are conducting experiments to determine if methane hydrates can serve as a solution to the energy

5H2O 2) There are at least two reasons why heating to find percentage of water in hydrated crystals is not recommended for all hydrates. The first reason is that some hydrates have such a strong bond with the water that not all of it will be able to be removed. The second reason is that different hydrates have their own mass. Depending on the mass and type of hydrate‚ some of the molecule may be burned off from heating. This would lead to a false accusation that the mass loss was all from water

Title: Formation of a Salt Objective: Students will observe the reaction of NaHCO3 and HCl. Students will draw the Lewis Electron Dot Diagrams of Na+ and Cl-. Students will site examples of how to identify an ionic compound. Materials: Materials include 6M of HCl and NaHCO3 ‚ a 100 milliliter (mL) beaker‚ a 10 mL graduated cylinder‚ a dropper‚ phenol red indicator‚ distilled water‚ a hot plate‚ a balance‚ a magnifying glass‚ and beaker tongs. Procedure: First‚ measure the mass of

Determine that all the water has been driven from a hydrate by heating your sample to a constant mass. Relate results to the law of conservation of mass and the law of multiple proportions. Perform calculations by using the molar mass. Analyze the results

The Formation of Alum Experiment 4 Introduction In an increasing population the need for land fields are as well increasing daily. Better yet‚ rather than dumping off trash is to instead recycle aluminum cans for a more efficient society. In this lab we will show how aluminum cans react to form alum. Materials and Methods The first step of the lab is to measure the mass of 250 mL beaker‚ once you have done this add .9 to 1.2 grams of aluminum can pieces to the beaker. Take the mass once

Experiment 5 – Percent Water in a Hydrated Salt Pre-Lab Hints 1. Note definition of deliquescent in the introduction. 2. See side notes for part A‚ as well as part 1 of Technique 15C (pg 27). 3. Mass of water in sample is the mass lost by heating (initial minus final). Water % is 100 times the g of water divided by the initial g of hydrate sample. 4. a. See step A1 in the procedure. b. A hot sample on the balance creates air currents and causes thermal expansion‚ both of which decrease
