The most significant decrease in the absorbance was observed after 10 minutes of incubation By the end of the experiment (30 hours later , the absorbance was observed to be 1 /16th of the initial absorbance recorded Graph of concentration time versus

time (24 ml /min

The concentration of the solution decreased through time . The initial drop in the concentration could be observed from the start to the first 10 minutes of the experiment . It has been observed that at the 25th through the 30th minute or time interval , there was a minimal decrease in the concentration of the solution

The absorbances recorded decreased through time . The most significant decrease in the absorbance was observed after 25 minutes of incubation By the end of the experiment (30 hours later , the absorbance was observed to be 1 /50th of the initial absorbance recorded

Graph of concentration time versus time (50 ml /min

The concentration of the solution decreased through time . There was an initial increase then a quick drop in the concentration that could be observed from the start to the first 3 minutes of the experiment...
