Determination of the Waters of Crystallisation/ Water of Hydration‚ In Hydrated copper (II) Sulphate Introduction In nature there are some salts that will have water in their crystalline structure. These salts are commonly known as hydrated salts. Hydrated Copper (II) sulphate is one of these‚ as suggested by the use of the word hydrated in its name. Its molecular structure is shown below. The water that is chemically combined into their structure is called the water of crystallisation.

Calculating the Enthalpy Change of Reaction for the Displacement Reaction between Zinc and Aqueous Copper Sulphate Data Collection and Processing Observations: * Drops of water left on the inside of the measuring cylinder * Hole in the lid‚ possible escape route for gas or splash-back * The polystyrene cup felt warm during the reaction By extrapolating the graph we can estimate what the rise in temperature would have been if the reaction had taken place instantaneously. I can

EXPERIMENT 1: Aim: To range the metals copper‚ lead‚ silver and zinc together with hydrogen. Start with the strongest reducing agent. Hypothesis: The nobler a metal is‚ the worse reducing agent. Apparatus/requirements: Sandpaper‚ strips of; zinc‚ lead‚ silver and copper‚ solutions containing aqueous; Zn2+‚ Pb2+‚ Cu2+ and Ag+ ions (0.2 M)‚ hydrochloric acid (5.0 M)‚ emery paper‚ test-tubes. Method: Burnish the three metal strips to get a shiny surface‚ after drop a drop of each of the metal

A series of dilution of known concentration is performed from the phosphate working solution. Each of the prepared working standards‚ the unknown samples and the blank are then made to react with a mixed reagent which have been prepared after acid wash of the glasswares Glassware * 2 Beakers * 11 conical flasks

The Chilean Cooper Mine Mary Carver BCOM/275 Allan Stallings September 20‚ 2012 The Chilean Cooper Mine cave in 2010 trapping 33 workers for 17 days 2‚300 feet underground was a tragic accident that they could have been prevented if the company would have had a strategic business plan in place for this type of crisis ("Chile Mining Accident (2010)"‚ 2011). A crisis management plan is crucial to have in a mining company‚ but every company large or small should have one. No business plans

that have been crystallized from water solutions appear to be perfectly dry‚ yet when heated they discharge large quantities of water. An example can be hydrated copper (II) sulfate. Exactly this salt is used in the described experiment.

electrolysis. An investigation to find out what factors affect the rate of electrolysis of a solution containing copper (II) ions. Plan It is known that by passing a constant electric current through a copper sulphate solution the passage of ions through this solution results in copper atoms being dissolved into the solution from the anode‚ which has a positive charge while positive copper‚ ions (cations) are also being discharged at the cathode which has a negative charge. Normally anions‚ which have
