For this experiment we tested the absorbency of copper sulphate in different concentrations to prove the Beer Lambert Law. Introduction: This Law: Provides an experimental link between the absorbance properties of a solution of a given compound and its concentration. This is normally expressed as . A = Absorbance measured = Absorptivity C = Molar concentration L = Length of cuvette Equipment: • Gilson pipette • Eppendorf tubes • Copper sulphate • Spectrophotometer • Cuvettes • Distilled

that was going to occur when the two substances‚ iron and copper(II)sulfate‚ were mixed together in water. Seeing that iron was going to displace copper and take its place‚ it was chosen to be the limiting reagent with the condition that if it was in excess then after the displacement was completed‚ there will be iron precipitate left in the solution thus‚ we will not be able to identify and filter the copper metal. To weigh the amount of copper produced after it was filtered it first needed to dry out

reactivity of an element is related to its tendency to lose or gain electrons. Three metal strips that were used are copper‚ lead and zinc as well as the solutions of silver nitrate‚ copper(II) nitrate‚ lead(II) nitrate‚ magnesium sulfate and dilute(3M) sulfuric acid. The copper metal strip was placed in the silver nitrate and dilute(3M) sulfuric acid‚ the lead metal strip was placed in the copper(II) nitrate and the zinc metal strip was placed in the lead(II) nitrate‚ magnesium sulfate and dilute(3M) sulfuric

So today’s experiment is going to discover the relationship between mass of Copper(II) Chloride dehydrate and aluminum foil. In this experiment‚ the conditions are not ideal‚ so there will be limiting reactant and excess reactant. By finding the limiting reactant‚ it is easy to find the excess reactant and the mass of each reactant

Oxidation and Reduction Mnemonic: OILRIG Oxidation Is Loss‚ Reduction Is Gain Oxidation → the loss of electrons from an atom or an ion→ always happens at anode (positive electrode) → think anOde (O2 in the electrolysis of water xp) Redox reactions: Reactions involving the transfer of electrons e.g. burning‚ rusting‚ photosynthesis‚ respiration and the browning of apples. happens in three types of reactions: 1. addition of oxygen 2. removal of hydrogen 3. increase in valency (how easily an atom

inherited disorder were extra copper builds up in the liver‚brain and eyes. Wilson’s disease is an autosomal recessive trait. (Autosomal recessive trait: means two copies of an abnormal gene must be present in order for the disease or trait to develop) Wilson disease is located on chromosome 13. The gene is called ATP7B and it contains the genetic information necessary to make a copper transport copper out of the liver. Mutations in the gene lead to an abnormal copper transport

experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test tube‚ the color of the solution changed from sky blue to teal blue‚ a slight color change but still noticeable‚ and heat was released

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: 1. Measure the mass of the beaker and stirring rod. 2. Add 4g hydrated copper (II) sulfate
