Testing Unnatural Urine Trials


The essence the experiment is to identify the focus of urea in the unknown urea answer.


1 function with the kidneys is always to regulate the concentration of urea in urine. With this experiment the enzyme urease acts as a natural catalyst and speeds up the reaction rate. The urease breaks down the urea and creates carbon dioxide and ammonia


The 6 boiling pontoons contain urea, agar gel and a pH signal. The gels inside the hot tubes include bromothymol blue which gives it its yellowish colouring and tube has become acidified with citric acid solution. Once the chemical urease have been added to the boiling tubes and still left for 24 hours the agar solution will change blue in colour suggesting the production of ammonia through the breakdown of urea. The measurement extracted from the green gel within the boiling is going to determine the quantity of ammonia produced.

Equipment and Materials

The gear used in this kind of experiment consists of; 6 boiling tubes that contains acidified sugars with bromothymol blue indication, six arreters for the boiling tubes, 7x2cm3 syringes, urea alternatives (prepared in advance). The urea focus within the solutions are (mMol) 31. your five, 62. 5, 125, two hundred and fifty, 500. The gear also covered an urea solution with an unknown attentiveness and urease solution.


First 2cm3 of urease was added to each of the 6 test tubes which included the acidified agar (using one of the seven syringes) then using the leftover syringes 2cm3 of the urea was included in five in the boiling pontoons, each cooking food tube finding a different concentration of urea added to that using a clean syringe everytime. 2cm3 of the unknown attentiveness of urea was in that case added to the sixth cooking food tube. The stoppers were put into the boiling pipes and they were left inside the same space for 24 hours. After 24 hours the size of the green agar was measured plus the results documented in the stand of benefits below and plotted...
