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

Lab #6 Properties of Hydrates Purpose: The purpose of the “Properties of Hydrates” lab is to study hydrates‚ and be able to identify them. This lab also focuses on observing the reversibility of hydration reactions by hydrolysis‚ and also testing substances for efflorescence of deliquescence. Procedure: A. Identification 1. Place 0.5 grams of each compound (Nickel Chloride‚ Potassium Chloride‚ Sodium Tetraborate‚ Sucrose‚ Calcium Carbonate‚ and Barium Chloride) in a small dry test

Abstract: Hydrates are compound with a constant composition. Concepts of Law of Definite Proportions (hydrates remain in constant proportions) and Law of Conservation of Mass (this idea is used to determine the mass of water in the compound and‚ subsequently‚ the formula of the compound) are expressed in this experiment. In this experiment‚ the goal was to find the formula of copper sulfate pentahydrate by heating a sample of the blue compound in order to evaporate the water and receive the

Friendship Fountain was the largest and tallest fountain of its time. It was designed in 1963 by the architect Taylor Hardwick‚ and took two years of building up until the park opening in 1965 (Godwin). It was renamed in 1968‚ after the park’s finance commissioner Dallas Thomas was involved in scandals and indicted. It then became known as the “Friendship Fountain” at the suggestion of the members of the Rotary Club‚ whose club principles included strong friendship (“Friendship Fountain Grand Reopening”)
