Properties of complex ions Essay 1732 Words | 6 Pages
PurposeThe purpose of this experiment is to look into some belongingss of ionic composite compounds which contain H2O molecules, viz. experiments of bluish Cu ( II ) sulfate hydrated. The figure of co-ordinated H2O will be determined.IntroductionThe computation of the value of x ( the figure of combined H2O ) is based on the 'relative molecule mass ( Mr ) ' and 'the mole ' . Lister and Renshaw ( 2000 ) stated that, Mr is the mass of a molecule compared to the mass of 1 H atom, and is the amount of the comparative atomic mass. The figure...
Group 2A: The Alkaline Earth Metals Essay 674 Words | 3 Pages
Introduction:This lab was divided into four parts: Part 1 was about testing for hydrogen gas. Part 2 involved finding the pH levels of certain elements.Part 3 was about testing for solubility.Part 4 was simply taking in the observations and making them make sense.Procedure:Part 1: 1) Pour about 2.5 mL of distilled water into a clean, dry test tube and stand the tube in the test tube rack. Add a calcium turning to the water in the tube. To collect gas being released, invert a clean, dry test tube holder.2) Test for hydrogen gas by inserting a burning wood splint into...
AMMONIUM NITRATE Essay 635 Words | 2 Pages
SCIENCE REPORTAMMONIUM NITRATENH4NO3ProblemOur task was to investigate what the optimum ratio of solute to solvent that will produce the maximum cooling/heating effect?HypothesisWith a smaller quantity of water (50mls) and the same amount of Ammonium Nitrate added. After any period of time the mixture will be a cooler temperature than that of a mixture with a larger quantity of water.Variables,XWater,XTeaspoons,XTime,XAmmonium Nitrate,XThermometer,XStirring (used thermometer),Changed/Uncontrolled Variables-The amount of times the mixture was stirred. We stirred the mixture until the Ammonium Nitrate was dissolved, so the amount of times we stirred after each teaspoon was different. -Each teaspoon may not have been equal. Measurements...
Chemistry Redox Reactions Explained Sample Essay 1824 Words | 7 Pages
HOW ARE REDOX REACTIONS DIFFERENT?Redox is the term used to label reactions in which the credence of an negatron ( decrease ) by a stuff is matched with the contribution of an negatron ( oxidization ) . A big figure of the reactions already mentioned in the Reactions chapter are redox reactions. Synthesis reactions are besides redox reactions if there is an exchange of negatrons to do an ionic bond. If chlorine gas is added to sodium metal to do Na chloride. the Na has donated an negatron and the Cl has accepted an negatron to go a chloride ion...

Lab 4: Titration of a Redox Reaction The purpose of this experiment is to standardize a solution of Mohr's salt, and to use titration to determine the volume ration of ferrous solution to the permanganate standard and calculate the concentration of the ferrous solution. First, Mohr's salt was mixed with H2S04. Then, the solution was titrated until the end point was reached. The volumes were recorded, and used to calculate the molarity of the ferrous solution. The major findings in this lab were that titration in a redox reaction an be used to find the concentration of one solution if...
Report on cobalt (III) ammine complexes 843 Words | 4 Pages
Introduction Cobalt was discovered by Georg Brandt in 1735 interestingly the name Cobalt originates form the German word `` Kobald '' which means hob or evil spirit. The original usage of Co was value to early civilization of Egypt for coloring glass blue. Alfred Werner was a innovator in coordination Chemistry determined the isomer Co ( III ) hexamine chloride. Experimental Ammonium chloride ( 1.306g ) was dissolved in dressed ore ammonium hydroxide solution ( 10.5cm3 ) organizing a colorless solution. Colablt ( II ) chloride hexahydrate ( 2.494g ) was added in little parts with t stirring bring forthing...
Chemistry: Water Pollution Phosphates In Water Pollution Phosphates Ma Essay 864 Words | 4 Pages
y be created by substituting some or all of the hydrogen of a phosphoric acid by metals. Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary or tertiary phosphate. Primary and secondary phosphates contain hydrogen and are acid salts. Secondary and tertiary phosphates, with the exception of those of sodium, potassium and ammonium are insoluble in water. Tertiary sodium phosphate is valuable as a detergent and water softener. The primary phosphates tend to be more soluble.Phosphates, which are an important component to metabolism in both plants and animals, help in...
