compounds (sulphates) were combined, they will react according to the Activity Series of metals. In our experiment we hypothesized that when magnesium metal and copper sulphate combines, it will produce an aqueous solution of magnesium sulphate and copper metal. When zinc metal and iron sulphate are combined, an aqueous solution of zinc sulphate and iron metal is produced. When iron and tin chloride are combined, iron chloride and tin are formed. When tin is combined with copper sulphate, an aqueous

Determining an enthalpy change of a displacement reaction Aim: To determine the enthalpy change for the displacement reaction between zinc powder and copper (II) sulphate solution. Zn (s) + Cu2+ (aq) → Cu2+ (s) + Zn2+ (aq) Theory: For the displacement reaction, an excess amount of zinc powder is added to the measured amount of aqueous copper (II) sulphate. The temperature change over a period of time has to be measured and thus, the enthalpy change for the reaction can be measured. The equation of the above

Introduction: The Voltaic, or Daniel cell, is an electrochemical cell, invented in 1836 by a British chemist, Frederic Daniel. The cell produces electricity through a redox reaction. The combined electric potentials of two metals in the metal sulphate solution of the electrolyte generate voltage. If the concentration of one of the electrolyte solutions is increased, the number of cations and anions increase (depending on which electrolyte you increase), which increases the overall voltage potential

Chemistry Title: voltaic cell experiment a voltaic cell is a device made from connecting two different metals together and immersing the combined piece into some sort of solution that creates conductive atmosphere , the general purpose of a voltaic cell is to convert the chemical reaction between the metals and the solution into an electrical charge , Hypothesis: the voltage produced by magnesium and cupper = the sum of the voltage produced by magnasium and iron ; and iron and cupper

following experiment six solutions were mixed with each other (groups of twos) in test tubes to test which reaction will result in an insoluble solid. See method for more detail. It is expected that the following compounds will form precipitates Silver Sulphate, Copper Hydroxide, Copper Iodide, Silver Hydroxide, Silver Iodide, Cobalt Hydroxide and two Silver Chlorides. This was worked out

International School of London Qatar By Hanad KC Finding The Formula of A Hydrate Objective To find the molecular formula of a certain hydrate of Copper (II) Sulphate, CuSO4, XH2O Apparatus • Ceramic Evaporating Dish • Electronic Balance • Bunsen burner • Clay Triangle • Glass stirring rod • Spatula • Crucible tongs • Copper (II) Sulphate hydrate crystals Method 1.

chondroitin sulphate conjugated lipid nanocarrier i.e. solid lipid nanoparticles (SLNs) for the effective management of RA. The SLNs were prepared by solvent injection method and further they were surface engineered with Chondroitin sulphate. They were further characterized for size and its size distribution, shape and surface morphology, zeta potential,

not controlled How the variable was controlled Concentration of the acid The denser the solution, the slower the reaction. The slower the reaction, the less copper is deposited in the given time period. Everyone used the same amount of copper sulphate solution Current passed through the circuit If it wasn’t constant then the time, intervals wouldn’t be equal. If the current is larger, there will be more electrons flowing around the circuit and more copper will be deposited. The use of a ammeter

Date: Introduction We are studying the reaction between zinc and sulphuric acid, the reaction is catalysed by copper sulphate and this experiment is to test whether the amount of drops effect the rate of reaction.
