INTRODUCTION: The purpose of this experiment is to measure the formation constant of the tetraamminecopper(II) ion by colorimetry. Anhydrous copper sulfate (CuSO4) is white‚ which means that it does not absorb light in the visible region of the spectrum. The hydrated copper sulfate (CuSO4 - 5H2O) is blue. The structure of the compound can be represented more accurately as Cu(H2O)4 SO4 - H2O where four water molecules are bound to the copper ion and the fifth is a water of crystallization. The

Procedure Access the virtual lab and complete the experiments. Part One (Flame Test): 1. Create and complete a data table for Part One of the lab. It should include the name of the element (or unknown) examined and the color of the observed flame: Barium-green Calcium-red Sodium-yellow Rubidium-purple Potassium-blue Lithium-pink 2. Identify each unknown from Part One of the lab and briefly explain why you identified each unknown as you did.: Unknown 1-yellow. I think it is Sodium because

Using chemistry for electronics and vice versa The microelectronics industry is continually striving to miniaturize conventional silicon-based electronic devices to provide higher performance technology that can be housed in smaller packaging. Progress resulting from this miniaturization is evident from the rapid advances in consumer electronics‚ such as cell phones and laptop computers‚ that have been observed in recent years. Now‚ silicon-based molecular electronics -- a complementary technology

Discussion The purpose of the Density Lab was to determine the identity of four unknown solids and two unknown liquids by calculating their densities and comparing them to a density chart‚ taking into account error analysis and finally classifying the substances. In order to calculate this density‚ we first found the mass of the container that was to be holding the substances. We then found the volume of the substance‚ and lastly determined the mass of the container and substance. We subtracted

+ 5 Fe+² + 8H+ → Mn+² + 5 Fe+³ + 4H2O (3) Potassium permanganate is widely used as an oxidizing agent in volumetric analysis.Since the MnO4 ion is a deep pink-violet colour and the Mn2+ ion is nearly colourless‚ the end point in titrations using KMnO4 can be taken as the first pink colour that persists in the solution. In titration ‚ permanganate solution is put in the burette and is run down to an acidified solution of reducing agent‚ e.g..ammonium iron(II) sulphate solution.In this experiment

Experiment 1 General hyphothesis and operationalisation: The general hyphothesis of this experiment is that any change in the physical body (Körper) has a detectable change in the lived body (Leib). Again‚ the concepts are meant in the use of the phenomenological tradition described in section one. Thus‚ Leib is the unthematised‚ subjective‚ immediate body consciousness‚ whereas Körper is the objective‚ material (physical) aspect of our body. Independent variables: Heart Rate was measured for

9/19/2012 Experiment #1-Density Aim: Learn how the process of distillation occurs. Observe how distillation separates alcohol from wine. Method: Distillation is based on the fact that the matter can exist in three phases - - solid‚ liquid and gas. As the temperature of a pure substance is increased‚ it passes through these phases‚ making a transition at a specific temperature from solid to liquid (melting point--mp) and then at a higher temperature from liquid to gas (boiling point--bp).
