Sodium thiosulfate

Equation of trendline 1 calculation: m= rise/run = 12/15 = 0.8 c= 5.9 y= 0.8x + 5.9 Equation of trendline 2 calculation: m= rise/run = 25/45 = 0.5 c= 17.6 y= 0.5x +17.6 Point of intersection: Equate both trendlines to find point of intersection 0.8x + 5.9 = 0.5x + 17.6 x= 39 Since x=39, x2= 9 as x2 represents x in descending order. R2: R2 for trendline 1 = 0.98 Correlation coefficient for trendline 1= 0.96 R2 for trendline 2 = 0.98 Correlation coefficient for trendline 2= -0.99 Ratio…

I predict that the higher the temperature of the solution the faster the reaction will take place because the particles will collide more when the temperature rises. The aim of this experiment was to test if the temperature affects the rate of reaction between hypo and dilute hydrochloric acid? How does temperature affect the rate of reaction between hypo and dilute hydrochloric acid? The kinetic particle theory explains the properties of different states of matter. The particles in solids,…

care to avoid adding air to the liquid being collected. Fill bottle completely and add stopper. 2. Remove bottle stopper and add 1 mL of the manganous sulfate solution at the surface of the liquid. 3. Add 1 mL of the alkaline-potassium iodide-sodium azide solution at the surface of the liquid. 4. Replace the stopper, avoid trapping air bubbles and shake well by inverting the bottle several times. Repeat shaking after floc has settled halfway. Allow floc to settle a second time. 5.…

Fresca Wine and the last is a mixture of ethanol and water that was made by me. The three different methods compared are the redox titration method which involves the oxidation of ethanol to ethanoic acid and then titrating the residue with sodium thiosulfate, which would then be used to calculate the number of moles of ethanol present in the original sample. The method of distillation involves heating the samples to the boiling point of ethanol causing it to evaporate from the liquid and then…

(I) nitrate salt solution is combined with the soluble sodium chloride salt solution, a white precipitate of silver (I) chloride is produced. (Source) Silver can also be dissolved using thiosulfate solution. However, studies have shown that the resultant AgNO3 electrolyte is considered to be ideal for further silver recovery via electrolysis or precipitation processes is due to its high recovery performances than that of the silver thiosulfate electrolytes. AgNO3 would seem to overcome the…

Principle: Principle of the method Modified Jacobs & Hochheiser Method (IS 5182 Part 6 Methods for Measurement of Air Pollution: Oxides of nitrogen). Ambient nitrogen dioxide (NO2) is collected by bubbling air through a solution of sodium hydroxide and sodium arsenite. The concentration of nitrite ion (NO- 2) produced during sampling is determined calorimetrically by reacting the nitrite ion with phosphoric acid, sulfanilamide, and N-(1-naphthyl)- ethylene diamine di-hydrochloride (NEDA) and…

production of iron oxide or what we know as rusting. 〖Fe〗_((s))+O_(2(g)) □(→┬ ) 〖Fe〗_2 O_(3(g)) In the rusting reaction iron is being reduced, and the oxygen is being oxidized. The most common oxidizing agent in bleaches from our experiment is sodium hypochlorite. The bleach that was used in this experiment was made by bubbling chlorine into the hydroxide solution. Some of the chlorine is converted to the hypochlorite ion but there is also some that turns from gas to aqueous. The chemical…

oxidation of 9-fluorenol, which is the decrease of a molecule’s hydrogen content.6 The following chemicals were used in the experiment: 9-fluorenol, sodium hypochlorite (the oxidizing agent), sodium thiosulfate (the reducing agent), sodium bicarbonate, acetic acid, and acetone.3,6 To begin the experiment 9-fluorenol, acetone, acetic acid, and sodium hypochlorite were added in sulfate is added to remove excess water from the hexane layer that is collected using the separatory funnel.6 To…

return back to iodide particles once combined with the second reaction or, more specifically, the sodium thiosulfate. This is due to equilibrium, which maintains a balanced state (by shifting to either the right or the left) despite the formation and consumption of several particles involved, simply meaning these equations are reversible - this is Le Chatelier’s Principle. After the sodium thiosulfate has been entirely consumed by the once triiodide ions, the iodide ions now react with the…

for the experiment is how a cold pack can be improved. The problem statement is “Which chemicals would work best at lowering the temperature of water to improve a cold pack?”. The Independent variables are the are three chemicals, ammonium chloride, sodium chloride, and calcium chloride, that will be added to the water. The dependent variable is the temperature of the water in degrees Fahrenheit after the chemicals are added. The constants are the 50 mL of water in each cup, the temperature of…
