ratio of mole between anhydrous copper II sulfate and the water vapour by using the formula: In this case‚ the molar mass of: Copper II sulfate (CuSO4) is: 63.55 + 32.06 + 15.99 x 4 = 159.57 g/mol Water (H2O) is: 1.01 x 2 + 15.99 = 18.01 g/mol (e.g. 0.37/18.01= 0.02054 mol.) Then‚ is obtained by: Calculation 1st attempt 2nd attempt 3rd attempt Mole of water (mol) = 0.06163 Mole of anhydrous copper sulfate (CuSO4) (mol) = 0.00394 = 0.00789 = 0.01184

firsts reaction involved adding hydrated copper (II) sulfate in water. The initial and final temperatures were recorded‚ and the ∆T of the trials were calculated. As the reaction was endothermic‚ which means it absorbs the heat‚ the temperature goes down and therefore the ∆T of the reaction is positive. The table below represents the information about the experiment: Data collection and processing of the dissolution of hydrated copper (II) sulfate ΔH/mol of the solution was calculated by the

Determination of Water in a Hydrate DESIGN – Aspect 1: Defining the problem & selecting variables Research Question: What percentage of Copper Sulfate Hydrate is water? Background Information: There are many ionic compounds that contain one or more waters of hydration in their formulae. They exists either in anhydrous or hydrated form. Most anhydrous compounds have a strong tendency to absorb water from the humidity in the atmosphere and shifts into a hydrated form. Because of

Sodium Laureth Sulfate: Common use -A detergent cleansing agent‚ cleanses and emulsifies properties - Sodium laureth sulfate is often used in laundry and hand dishwashing detergents. In addition‚ it can be found in cleansers‚ carpet cleaners‚ toilet cleaning products‚ stain & odor removers‚ all-purpose cleaners‚ etc. Importance of chemical in the item -An effective foaming agent -An anionic detergent and surfactant - Sodium laureth sulfate works well as a degreaser.

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 numerous steps. First‚ one had to safely prepare by putting on goggles. One then had to wash and heat the dish with the flame for about three minutes. After allowing the dish to cool‚ one had to weigh the evaporating dish and record the weight. Two to three grams of copper sulfate hydrate was then added to the dish
