that are formed from a reaction between an acid and a base. Hydrates are inorganic salts which contain specific numbers of water molecules. Not all hydrates contain simple formulas. According to Formula of a Hydrate‚ to be anhydrous is to be without water‚ or to have all water removed. Some hydrates can become anhydrous by heating them‚ meaning hydrates can be separated into salts and water after heating. An ionic hydrate is a hydrate with water molecules attached to a crystal lattice instead of

Copper Sulfate Pentahydrate Purpose: To verify the formula for copper (II) sulfate pentahydrate by measuring the amount of water decomposed from the hydrated species. MSDS: Copper sulfate pentahydrate- Harmful if swallowed. Causes skin irritation‚ causes serious eye irritation. Very toxic to aquatic life with long effects. If copper sulfate stays in the stomach‚ the victim becomes unconscious. The symptoms of poisoning include diarrhea‚ headache and injury to vital organs. Background: 1

For this experiment me and my lab partner didn’t finish the experiment. We only end up to adding the magnesium sulfate. We added so much magnesium sulfate‚ and ended up drying the whole product without any liquid left. We were trying to do the procedure all over again but‚ we will ended up to not finishing the experiment still due to time constrain. I will try to explain the possibility what will happen up to the end of the experiment. After measuring the 10ml graduated cylinder‚ which is 27.27g

9-19-13 Dehydrating and Rehydrating a Hydrate Introduction The mass percent of water was determined using the mass of water and dividing it by the total mass of the hydrate and then multiplying that answer by 100%. The number of moles of water in a hydrate was determined by taking the mass of the water released and dividing it by the molar mass of water. The number of moles of water and the number of moles of the hydrate was used to calculate the ratio of moles of water to moles of the sample

This experiment contains three separate procedures in which Aluminum Potassium Sulfate(Alum) will be melted‚ massed out and mixed with Barium Nitrate‚ along with distilled Water. Procedure one we completed two trials of melting two separate 0.01g of Alum and making a comparison to the literature temperature of 92.5‚ to do this we attached an Alum filled capillary tube to a thermometer and inside a beaker placed over a Bunsen burner. Procedure two consisted of placing 2.00 grams of Alum into a crucible

Unit 6 Lab Report 1. Objective: To find the percent composition of water in an unknown hydrate. 2. Materials: Goggles‚ apron‚ evaporating dish‚ hot plate‚ and stirring rod 3. Procedure: get the mass of a evaporating dish‚ put a sample of the hydrate onto the evaporating dish and mass the dish with hydrate. Put the dish with hydrate on the hot plate on high heat. Break up any clumps that form during the heating process. Observe any color

DETERMINATION OF THE CHEMICAL FORMULA FOR A HYDRATE USING MOLE RATIO OF WATER MASS AND MAGNESIUM SULPHATE INTRODUCTION Ionic (salt) compounds are able to hold loose bonds with water molecules. A hydrate is a compound that incorporates water molecules into its crystalline lattice structure (McGraw-Hill Ryerson‚ 2014). Identifying a compound as hydrated or anhydrous is important as the mass of the compound increases if it contains water molecules. In nature‚ hydrates exist with a fixed ratio of water

Percent Water in a Hydrate PURPOSE To determine the percent water in a hydrate sample. INTRODUCTION Many substances contain water molecules as a part of their crystal structure. We call such solids hydrates‚ and we call the bound water the water of hydration. A hydrate has a definite number of water molecules bound to each anhydrous salt unit. The formula of the hydrate copper(II) sulfate pentahydrate is CuSO4 · 5 H2O The dot indicates that the molecules of water are attached to the ions in

The mean data observed show a number of trends. The average weight and length tend to decrease as the amount of Ammonium Sulfate approaches the full recommended dose. On the other hand‚ the average amount of protein per gram of tissue tends to increase as the amount of Ammonium Sulfate approaches the full recommended dose. Our null hypothesis was that there is no difference between the mean weights or the mean lengths of the seedlings two different treatments. (A+B‚ A+C‚ and B+C) Each of these

The purpose of this lab was to study the composition of hydrates. Hydrates are ionic compounds that are chemical compositions made of water and salt. A main objective was to remove water from the hydrate by heating‚ and determine the amount of water that was in the hydrate. After doing this‚ one had to predict the empirical formula for hydrated copper sulfate. In doing this lab‚ one was able to see the gradual change in the composition of a hydrate into an anhydrous salt. The lab was carried out with
