Potassium iodide

determine the concentration of oxidizing solution using the iodine/ thiosulphate titration where the reducing solution is potassium iodate solution and the oxidizing solution is sodium thiosulphate solution. Potassium iodate solution which is an oxidizing agent is added into an excess solution of acidified potassium iodide. This reaction will release iodine. Potassium iodide is acidified with sulphuric acid and the iodine released quickly titrated with sodium thiosulphate until it become light yellow

Chemistry Lab Report (Design) Factors affecting Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases), Temperature, Presence of a Catalyst, Surface Area of the reactant, and Concentration. According to

orange-red-brown color since iodide was colourless and since iodine is not very soluble in water. As the reaction was progressing, the coloured solution began to fade to orange, yellow and finally became colourless.  As these colour changes occur, the temperature of the solution was decreasing gradually until it has finally reached room temperature.  This change in colour was due to two factors.  First, all of the solid and dissolved iodine had reacted with the zinc to produce iodide and zinc ions, both of

Title: Measuring the Absorbance of Light of a Reaction Between Potassium Iodide (KI) and Iron (lll) Chloride (FeCl3 ) to Determine the Order and Rate Law Expression Introduction: The purpose of this experiment was to determine the order and rate law expression of the reaction between KI and FeCl3 . This was done by using a colorimeter to measure the absorbance of light of the solution over time.Originally, both solutions of KI & FeCl3 are opaque, but when mixed the solution changes to a darker yellow

The next lesson was, “Asking a stranger for something is the easiest way to ensure that he will not give it. Much better simply to show him a friend with a need” (62). In order to get supplies, the Swallow Man would create stories that make strangers feel bad for him or to make it seem like they have something in common. This is how their trust was gained. Only then would the Swallow Man mention anything they were looking for. Using this method, the Swallow Man could get food and supplies that strangers

and potassium iodide were used to isolate and purify pure solid lead iodide, and the differences in the limiting reactant and solid lead iodide was observed. The amount of solid lead iodide was calculated by the measuring the mass of which the solid lead iodide was created in before and after the purification of solid lead iodide. The purification and isolation of solid lead iodide was achieved in two different process with different results. In the evaporation collection, the solid iodide was created

My first procedure that I completed was the filtration. When I mixed the lead (II) nitrate and the sodium iodide together, I got a bright yellow liquid that turned out to be lead (II) iodide. I believe I did this part of the procedure correct because the color was not too pale and I did not use too much lead (II) nitrate or sodium iodide. I used the correct amount to get the results that were listed on the laboratory, In procedure D, Glassworking, cutting the glass came out great. I followed all

Why do certain metal ions give flame colours in this way? The elements have their outer

volts of electricity, meaning the compound contained both positively and negatively charged ions that move around to conduct the electricity. Potassium Sulfate has a solubility of 1 g in 8.3 mL of water, which matches with the results of the unknown being soluble in water (The Merck Index). Ionic compounds, a form of polar compounds, are soluble in
