Compare The Rate Of Reaction When Reacting With Dilute Hydrochloric Acid
The aim for this investigation is to investigate the effects of varying the concentration of sodium thiosulfate solution on the rate of the reaction when reacting with dilute hydrochloric acid.
It is hypothesized that as the concentration of the sodium thiosulfate solution increases, the rate of the reaction will also increase proportionately.
Variables
The independent variable is concentration. This will be varied by increments of 10mL (10mL to 50mL) and distilled water will be added accordingly to maintain a constant volume of 50mL.
The dependent variable is the rate of the reaction. This will be indirectly measured by using a stopwatch to measure how long the reaction takes to occur. The rate will be calculated by finding the reciprocal of the time taken for the reaction to occur.
The temperature of the solutions will be held constant by the experiment being conducted in one area of room …show more content…
From here, as concentrations increased, time taken for the reaction to occur appeared to decrease at an exponential rate. The fastest reaction occurred when the concentration was highest and took 25.29 seconds.
Figure 2 shows that as concentration was increased, the reaction also increased but at a decreasing rate. The correlation between the data and the exponential trend line was very strong with an R2 value of 0.998.
Precision
It is likely that the data is precise due to the data collected and shown in Figure 2 having a very strong correlation of
