Histology analysis There were five steps involved in histological preparation. Step 1: Dissection and tissues collection The testis tissues were cut with a sharp scalpel into slices of not more than 2-3 mm thick and 10 mm long. The fixation process was commenced immediately after removal of the tissue sample. The specimen tube was filled with 20 ml of 10% formalin. The tissue was placed inside the specimen tube. Step 2: Dehydration Dehydration process begins when the fixed tissues was

Abstract The chloride present in an unknown soluble sample was precipitated into silver chloride through precipitation gravimetry. The colloidal silver chloride originally formed was converted to a crystalline solid by controlling certain parameters of the experiment such as temperature‚ pH of the solution‚ and concentration of AgNO3. Once the solid was large enough‚ it could be washed‚ filtered‚ and weighed. The percentage of chloride present was found to be 24.73695223 (±0.00000006) %.

With the urine samples given to us by the five patients we tested the amounts of glucose‚ amino acids‚ urea‚ and salts in urine. To test this we used different chemicals that would react with one of the four items above showing either a high concentration or low concentration within the urine. By using a solution called silver nitrate we could test whether or not salt was present in the urine. If the urine turned a cloudy white after adding the silver nitrate the urine had a high concentration of
