Cloud seeding can be performed from the ground using a launcher with silver iodide cartridges‚ that get shot into the clouds. Or the process can be done from an aeroplane that releases the silver iodide into the clouds from above. Using aeroplanes is the preferred method as it is more accurate. Ground Based Cloud Seeding is used in places where there is low level clouds over difficult terrain

acidic medium. However‚ iodine is not very soluble in water (0.001M)‚ this makes the method less than ideal. Instead of dissolving solid iodine in water‚ we can obtain excess quantity of iodine solution by adding an unmeasured excess of potassium iodide solution to a known volume of an acidified standard potassium iodate solution according to the following equation: IO3-(aq) + 5 I- (aq) + 6 H+ (aq) 3I2 (aq) + 3H2O (l) Then the experiment is immediately followed by a back titration of the excess

Process Module 1 19 Aug 1999 SRI Consulting Process Summary This Aspen Plus model simulates the production of acetic acid by low pressure methanol carbonylation in the presence of a heterogeneous rhodium (Rh) catalyst and the promoter methyl iodide. It is intended to resemble the Chiyoda/UOP Acetica™ process‚ a novel heterogeneous methanol process for the production of acetic acid. This technology is based on a heterogeneous Rh catalyst in which the active Rh complex is chemically immobilized

out the effect of ethanol by carrying out the iodine clock reaction with and without ethanol present and the results will be compared to draw a conclusion. A2 AIMS: 4. Investigate the order of reaction with respect to hydrogen peroxide‚ iodide and acid. The goal of this aim is to find out what order of reaction each chemical produced by making a graph for each of the reactants and analysing the line of best fit. 5. Investigate the rate equation‚ rate constant and possible mechanism

double displacement reaction between the solutions Lead (II) Nitrate (PbNO3) and Potassium Iodide (KI). It is important to obtain amounts of Lead (II) Nitrate and Potassium Iodide as close to 1.44g as possible. This reaction creates Lead (II) Iodide and Potassium Nitrate. The precipitate during this reaction is Lead (II) Iodide. The balanced equation is Pb(NO3)2 + 2KI= PbI2 + 2KNO3. In this lab the Lead (II) Iodide is separated from the solution and collected so it can be weighed for a mass. Potassium
