Factors that affect the rate at which Sodium Thiosulfate (Na2S2O3) reacts with Hydrochloric Acid (HCl)

Examine factors that affect the reaction rate of sodium thiosulfate (Na 2 S 2 O 3) and hydrochloric acid (HCl). When sodium thiosulfate is mixed with hydrochloric acid, a reaction occurs, resulting in the formation of a sulfur precipitate. This makes the solution opaque. Use this turbidity to investigate factors that affect reaction rate. Temperature is temperature. To this end, sodium thiosulfate and hydrochloric acid are reacted at 5 ° C intervals in the temperature range of 20 ° C to 40 ° C to obtain five results.

In this survey we investigated how concentration influences the reaction rate of hydrochloric acid and sodium thiosulfate. Measure the reaction rate of hydrochloric acid added to sodium thiosulfate. Mixing sodium thiosulfate and hydrochloric acid produces a yellow sulfur precipitate. As more and more sulfur is formed, the solution becomes more and more difficult to understand. This is how I measure the reaction speed. Place the black crosspaper under the solution and stop the watch when the cross becomes invisible.

My aim in this study was to see the effect of temperature on the reaction rate in solution containing sodium thiosulfate in hydrochloric acid. The equation of the reaction occurring in the experiment is as follows. Sodium Thiosulfate + Hydrochloric Acid → Sulfur + Sulfur Dioxide + Sodium Chloride + Water? Among them, sulfur is an insoluble precipitate. - Study of reaction rate Study the reaction rate of magnesium with different concentrations of hydrochloric acid. To do the experiment, I need the correct equipment: * goggles * stop clock * beaker · 30 cm 3 cylinder · 5 x 70 mm magnesium belt · 1, 1.5, 2, 2.5, 3 mol / dm 3 hydrochloric acid · Gas injector Next, we need to set up the equipment, whi
