Sodium thiosulphate solution

iodide) to react fully with Peroxodisulphate ions (in potassium Peroxodisulphate). I will do three sets of experiments changing first the concentration of iodide ions, then the concentration of Peroxodisulphate ions and finally the temperature of the solution in which the reaction is taking place. From these results, I hope to draw conclusions as to the effects of these changes to the environment of the reaction on the rate and also determine the order of the reaction and the activation enthalpy.

Investigation How does the concentration of the sodium thiosulfate affect the rate of reaction to hydrochloric acid? contents page 1: contents, aim, prediction, equation, diagram page 2: equipment, preliminary experiments page 3: page 4: page 5: page 6: page 7: page 8: Aim: In my investigation I am trying to find out how the rate of reaction between sodium thiosulfate and hydrochloric acid gets affected but the concentration of the thiosulfate. Prediction: My prediction is that the increased

In experiment 2, temperature was the factor tested to see how it affected the rate of reactions. Tweaking the method for the first experiment, the sodium thiosulphate were in three different temperature; one was placed on a hotplate and heated, another in an ice bath and the last was room temperature. This showed how the temperature of the solution can be an important factor when investigating reaction rates. Concentration of the reactants affects reaction rate by increasing the rate when the concentration

I) Sensitizing reagent Sodium thiosulphate 0.2 g and Sodium acetate 6.8 g dissolved in ultra pure water. In the solution 30 ml absolute ethanol and added 0.5 ml Glutaraldehyde (25%) solution, the final volume produced to 100 ml with ultra pure water. II) Silver nitrate reagent 0.25 g of Silver nitrate dissolved completely in ultra pure water and 40.0 µl Formaldehyde (37%) solution added, to make final volume to 100 ml with ultra pure water. III) Developing reagent 2.5 g Sodium carbonate dissolved in

reaction rate, and that the highest temperature will have the fastest rate of reaction. The data also supports the hypothesis that as the concentration of Potassium Iodine increases so will the reaction rate, and vice versa for an increase in Sodium Thiosulphate concentration. The hypothesis that the Iron (II) ions will affect the reaction rate, and that the optimal amount will be about 0.1M of catalyst was partially supported. In Graph 1 the data shows an exponential rate of change as the molarity

Discussion: The tested elements in group I were Lithium, Sodium and Potassium. All elements were a silvery grey until they were tarnished as the element reacted with the oxygen. Group I elements have an oxidation state of +1 which they can lose to increase stability and form compounds. Melting and boiling points decrease as the elements move down the group. All elements had a reaction but potassium had a greater more rapid reaction than the others. This indicates that elements that are lower in

Title: The Effect Temperature of Sodium Thiosulfate Has On The Rate of Reaction with Hydrochloric Acid Statement of Inquiry: What is the effect of changing a factor on the rate of chemical reaction? Aim: The aim of this experiment is to observe how by increasing the temperature of sodium thiosulfate in a solution with 2.0 molar Hydrochloric acid can affect the rate of reaction and the rate in which a precipitate is formed. Hypothesis: If the temperature of the sodium thiosulfate is increased, then

KOH was used to allow oil be soluble in it. [1] Two to three pieces of boiling chips were added so as to prevent formation of large bubbles [1]. It was then subjected to reflux for an hour. After which, it was then cooled to room temperature. The solution was then transferred into an Erlenmeyer flask. Small amounts of hexane were added to rinse of remaining oil from the round bottom flask. It was then titrated with 0.5M HCl, using 1% phenolphthalein as the indicator. Volume of KOH used was used to
