Therefore, the cross will disappear more quickly due to the cloudiness of the solution. A more concentrated substance has more molecules for a given volume than a more dilute substance. Because there are more molecules about, the frequency of successful collisions is greater, and the reactions happen faster.
I can see that both graphs have a curved line. This tells me that there is a relationship when the concentration of the hydrochloric acid increased. As it takes time for the reaction to take place it is not have a linear relationship.
I can see that when the concentration of the acid is increased the reaction happens quicker. The quickest reaction was when the 2 molar acid was added and the slowest was the 0.
There is a curved line as in the 0. The graph supports my prediction and it show that as the concentration of the acid increases the quicker the reaction. There was an anomalous result marked as RED it may be because we did it over two days and the temperature may be different.
We may have stirred it faster so the acid particles collided faster with the Sodium thio-sulphate particles.
To get the average we did not include the anomalous result. Next time to make this experiment more accurate a data logger and a light sensor can be used. Also to do this experiment within one day will improve the accuracy and reliability of the experiment.
Another way to make the experiment more reliable is to measure a wide range of readings and also would repeat the experiment another time to improve the accuracy of the results.
The positive points of our experiment were that we measured the volume of each acid and the Sodium thio-sulphate. Also we washed each apparatus thoroughly so the reactants were not reacting before the test took place. To take this experiment I would keep the concentration of the acid the same but I would alter the concentration of the Sodium thio-sulphate or I could keep the concentrations of the reagents the same but change the temperature to see if there was any difference.
GET EVEN A BETTER ESSAY WE WILL WRITE A CUSTOM ESSAY SAMPLE ON The Rate of Reaction between Hydrochloric. These result in more effective collisions, therefore, the rate of reaction will be increased. Summary of the Lab: To begin the lab, 3M Hydrochloric Acid (HCl) and Sodium thiosulphate .
Published: Mon, 5 Dec The aim of this experiment is to study the rate of reaction and the different parameters that affect it. In this experiment, we will be investigating the effect of temperature on the reaction between Sodium Thiosulphate and Hydrochloric Acid.
Temperature has a large effect on the rate of reaction. For many reactions, an increase in temperature of just 10 °C will roughly double the rate of reaction. You can also monitor the rate of reaction between the sodium thiosulfate and hydrochloric acid by using a light sensor.
Nov 30, · Hydrochloric Acid And Sodium Thiosulphate: How Reaction Rate Varies With Sodium Thiosulphate Concentration acid and sodium thiosulphate: how reaction rate varies with sodium thiosulphate Concentration Introduction When sodium thiosulphate reacts with hydrochloric acid.
Factors affecting rate of reaction What is the effect of the concentration of sodium thiosulphate (Na2S2O3) on the rate of reaction with Hydrochloric Acid (HCl)?
