Copper sulphate

Spiking of soil with copper sulphate signficantly affected the survival of subadult C. aspersus snails. Adult specimens exhibited higher mortality percentages at 30, 44, and 70 days (between 46.20% and 60.20%) after being sprayed with 5% and 10% solutions of the same salt (Schwartz and Capatos, 1990). These results clearly show that copper sulfate is highly toxic to land snails. The death rates of controls were similar at 30 and 60 days post-exposure, and as a result, environmental factors appear

How has the extraction of copper changed the course of history? Copper (Chemical symbol Cu, Atomic number 29), is one of the best electrical conductors in all metals, has influenced the use of telecommunications throughout the world. We rely on copper for a lot of things - power, heating, lighting, transport, communication, and even coinage. The wide application of copper in our daily lives has made our homes, schools and businesses pleasant, decorative and efficient but also has created negative

Chemistry Research assignment OUTLINE the history of the development of the Periodic Table including its origins, the original data used to construct it and the predictions made after its construction. (Include references to the contributions made by Antoine Lavoisier, Johann Dobereiner, John Newlands, Dmitri Mendeleev, Lothar Meyer, William Ramsay, Henry Moseley, J.J. Thomson and Niels Bohr. In 1803 a man by the name of John Dalton Proposed that matter was comprised of atoms that were very simple

Understanding the ingredients of your dog's food items is a must for the dog lovers or dog owners. Whenever you feed the dog with different kinds of food items, you should always read the label and understand the contents about the dog feed types that are being used in such commercial preparations. You should understand the ingredients while buying food for your dog and also know what to look for. Feed items include dry and fresh food. The fresh dog food that is prepared in homes generally consists

Grouping elements with similar chemical properties together Date: 4.10.2012 Objectives The objective of this experiment is to experimentally investigate which elements show similar chemical properties. Chemical principle Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a dull gray, silver solid under standard conditions. Calcium atoms have an electron configuration of (2, 8, 8, 2) and 2 outermost shell electrons. Calcium is in group 2 and period 4 of the

Strontium nitrate, the limiting reagent, was poured into the copper(II) sulphate solution, the excess reagent, rather than the other way around. This is a minor systemic error, because even if some of the strontium nitrate remained in its initial beaker, the beaker was thoroughly rinsed out multiple times. The error causes the final mass of the filter paper and precipitate to be slightly decreased, as not all of strontium nitrate reacts with the copper(II) sulfate. This can explain why the percent yield in

result. After a chemical reaction has taken place, the outcome is chemical products. An example of a chemical reaction is when iron (III) sulfate and copper (II) are produced when copper (II) sulfate and iron (III) react together. In this circumstance, the reactants are iron (II) and copper (II) sulfate. The products are iron (III) sulfate and copper (II). The reactants are used up whilst new products are created. There are multiple types of chemical reactions that can

substances on the earth’s surface and is caused by many chemicals including sulfuric acid synthesized from sulfur dioxide and nitric acid from nitrogen oxides. Sulfur dioxide is mainly emitted into the atmosphere by smelters in Sudbury that process copper and nickel. In 1983, “Canada adopted a target

Ring Test- adding iron (II) sulphate to solution of a nitrate. Slowly adding concentrated sulphuric acid such that the acid forms a layers Indicating the presence of the nitrate ion. Sulphate (SO4 2-) Equation: 2M(NO3)2(s)  2MO(s) + 4NO2(g) + O2(g) Barium Chloride- A few drops of dilute hydrochloric acid are added to the solutiom A few drops of barium chloride solution are then added. The presence of a white precipitate of barium sulphate shows the presence of sulphate ions in the solution. Sodium

The discoveries as made by the IRATE (Illawarra Residents Against Toxic Emissions) have significantly impacted on the residents of the Port Kembla area. Since 1907, upon the opening of the Copper Smelter in the Port Kembla industrial area, residents have experienced periods of remaining silent in regards to their health/wellbeing, as well as periods of protest (Mitchell 2015). Two local residents whose experiences and discoveries became crucial to residential impact are Helen Hamilton and Olive Rodwell
