Copper II Chloride Dihydrate – [CuCl2.2H2O] is a solid which is soluble in water and alcohol. It appears in a fine light blue-green deliquescent crystal with slight hydrochloric odour (Material Safety Data Sheet, 2010). Copper II Chloride Dihydrate is used in different fields– both for agricultural and non-agricultural purposes. Agricultural uses include herbicides, toxicity tests, food production, pesticides, fungicides, feed additive, wood preservative and disinfectant (Material Safety Data Sheet, 2010). Non- agricultural uses are: as a catalyst for organic plating and inorganic reactions, in tinting baths for Iron (Fe) and Tin (Sn), in photography as a fixer, desensitizer and reagent, as mordant for dyeing and printing textiles, in indelible, invisible and laundry-marking inks, in metallurgy: in wet process for recovering mercury from ores and in refining copper, silver and gold, in pigments for glass and ceramics, in pharmaceuticals and textile industries, ornaments and dental amalgams (Material Safety Data Sheet, 2010). Copper (II) Chloride Dihydrate, also known as Cupric Chloride Dihydrate, is a copper-based product. The harmful effects increase with both the concentration and length of exposure. Copper is a common heavy metal pollutant in …show more content…
Consequently, there is the need to determine the level of toxicity of the toxicant to C. gariepinus juveniles. Thus, this study was conducted in order to assess the sub-lethal effects of Copper II Chloride Dihydrate on the histology and LC50 of C. gariepinus juveniles under laboratory conditions for guided/informed use and to help fisheries administrators in formulating policies that will control the uses of the chemical in the aquatic environment generally and also, will help fisher folks/aqua culturists to know the concentration that should be used for therapeutic and prophylactic
The main intention of this experiment is to distinguish whether the chemical Bisphenol A (BPA) has effects on Atlantic Croaker fish. Samples from Atlantic Croaker were taken from both tributaries, one being a Bisphenol A (BPA) free tributary, and the other being filled with Bisphenol A (BPA). In which data was recorded, analyzed, and had astonishing results. The results displayed that when the female Atlantic Croaker hepatic system were exposed to high dosages of Bisphenol A they showed physical abnormalities
The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate, CuSO4, mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was found to be 2.1726g which meant that through limiting reagent analysis Fe was determined to be the limiting reagent and the chemical reaction was determined to be as following:-
XIII. Carefully remove the copper metal from the filter paper onto the watch glass. (with a spatula) Place a 400 ml beaker on a hot plate contained with water. Carefully place the watch glass before the water boils to dry the copper metal. (Use the tongs to handle the hot watch glass)
Copper concentrations that exceed 20 micrograms per gram can be toxic to any living thing (Solomon). Copper binds easily to organic matter, which means it levels are rather high in animals that can filter materials from water; although biomagnification doesn’t occur in the food web. In terms of aquatic organisms and ecosystems, copper is one of the most toxic metals, and aquatic organisms tend to be more sensitive to its effects.
The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle, copper was present in different forms. First reaction involves reaction between the copper and nitric acid, and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into copper 2 oxide and water when heated. When solid CuO reacted with sulfuric acid, the copper returned to solution as an ion (Cu2+). The cycle of reactions was completed with the reaction where elemental copper was regenerated by Zn and Cu
Purpose: The purpose of this experiment is to form Copper (II) phosphate trihydrate and determine its actual yield by identifying the limiting reactant in the reaction. It also includes calculating the percent yield by finding the theoretical and experimental yield of the precipitate. The limiting and the excess reagents will be figured out using the mole ratios in the chemical formula. Procedure: For the first part of the experiment, 15 ml of copper (II) chloride solution and sodium phosphate solution was obtained in a 50-ml beaker.
Copper is a metal that has been used by humans essentially since the beginning of existence as it is said to be only the second metal used by man after gold. Therefore, copper production has been an important part of life for thousands or years and still is today. The copper cycle is an important because it provides a basis for how copper can be recovered from various compounds that it exists in during its so-called “life-cycle” . The life cycle of copper conserves this now scarce metal by allowing the recovery of the pure substance at any point through experimental means. While copper is much more, scare in earths natural environment today it is still an incredibly important product. Copper is used in manufacturing wiring for electricity as
The year 2011 may be remembered as the year when sailors started thinking differently about copper. After centuries of relying on toxic metals to ward off growth on the bottoms of boats, sailors are awakening to a new era of environmental consequences, greater regulation, and breakthroughs in science and paint technology. Generally, antifouling paints contain at least one biocide, an ingredient capable of poisoning marine life that would cling to the hull, but getting these toxins to work usually requires either friction or a chemical reaction. Florida has found 160 miles of estuaries contaminated with copper,
The reaction characteristics of basic copper carbonate 〖mCuCO〗_3⋅n〖Cu(OH)〗_2 were observed by changing the reaction mole ratio. The reaction mole ratio of sodium carbonate to copper chloride (II) was controlled from 1.08 to 1.68. Fig. 1 shows the XRD patterns of copper carbonate powder. At a reaction ratio of 1.08, paratacamite (Cu_2 Cl(OH)_3 ), beside alkali copper carbonate, was formed because of incomplete reaction at a copper content of 53.9 wt%. Lack of sodium carbonate may cause incomplete reaction with copper chloride (II) because of low pH (6.0) of the solution [12]. The copper content according to the reaction mole ratio were 57.7, 50.5, 58.8, 59.3, and 59.8 wt% at the reaction mole ratios of 1.20, 1.32, 1.44, 1.56, and 1.68, respectively.

Copper is an element commonly found in Keweenaw Peninsula near Lake Superior in Michigan. To the facts Copper has twenty nine electrons and a melting Point of 1083.0 °C (1356.15 K, 1981.4 °F) there are twenty nine electrons in the copper atom why because it is the atomic weight or atomic mass.
When writing chemical formulas for compounds with transition metals, the transition metal will always come first. For the copper(II) chloride example, you first write “Cu” for copper, followed by “Cl” for chloride. Since you determined you need two chloride ions when you balanced the compound, the complete chemical formula should read “CuCl2.” If you have a transition metal in a compound with a polyatomic ion, the polyatomic ion needs to go in parentheses. For example, chromium(II) bicarbonate’s formula is “Cr(HCO3)2.” Notice the subscript for the polyatomic ion is located outside of the parentheses.
NaCl is short for Sodium Chloride. Its commonly known as Salt, It is known for being the saltiness in seawater. In the form of table salt it is commonly used as a condiment and food preservative.Large quantities of sodium chloride is used in many industrial processes, and it is a major source of sodium and chlorine compounds. A second major application of sodium chloride is de-icing of roadways in sub-freezing weather.

The dangers of mercury contamination are well known, but copper is also toxic and is a problem. When it is ingested, it can "interfere with the metabolic machinery of the cells of these animals" (Marine pollution questions). Not only does this mean they will die off, not reproduce or be somehow otherwise impaired, thus decreasing the population.
