Creatinine Test Lab Report

If the HCl in the solution increases the pH of the water, it shows that HCl will increase the pH of the blood and if the HCl in the solution decreases the pH of the water, it shows that HCl will decrease the pH of the blood. 15. Add 10ml of 0.85% lactic acid into a beaker containing distilled water. 16. Measure the pH of the solution containing water and lactic acid.

FTIR Spectroscopic Study on Quantitation of Urea in Human BloodSerum Abstract: The quantitation of urea has been achieved using FTIR spectroscopy. The FTIR spectra of human blood serum samples are recorded in Mid IR region 4000-400 cm-1.The normal blood serum is treated with urea at different concentrations and FTIR spectra are recorded, which confirm the specific peaks related to urea. A plot between concentration of urea and percentage of absorbancehas shown linear relationship.

The purpose of this experiment was to perform a Wittig reaction using two different methods: In method I, 250 mg aldehyde was mixed with 785 mg phosphonium salt in 5 M NaOH solvent. This mixture was stirred for thirty minutes and filter by vacuum filtration for the product. In method 2, 250 mg of aldehyde, 785 mg, benzyltriphenylphosphonium chloride, and 380 mg potassium phosphate tribasic were homogenize with a pestle and mortar. Vacuum filtration was also used in this method to attain the product. The products in both methods were used for recrystallization and TLC.

Symptoms and indicators of UTI (hematuria, urgency, frequency, and nocturia) can also be present. A series of urodynamic reviews can also be applied to set up the form of bladder dysfunction and to support in making a alternative on suitable relief. A voiding diary can be utilized to furnish a written file of the quantity of urine voided and the frequency of voiding. Postvoid residual urine would even be assessed via using each and every straight catheterization or an ultrasound bladder scanner and is considered diagnostic of urinary retention. Mainly, residual urine quantities to not greater than 50 mL within the core-aged grownup and no more than 50 to 100 mL inside the older adult.

In addition, phenolphthalein was added as an indicator. The aliquots were titrated against sodium hydroxide (NaOH) solution until end point was reached, after which volume of NaOH consumed was recorded. The value of the rate constant, k, obtained was 0.0002 s-1. The experiment was then repeated with 40/60 V/V isopropanol/water mixture and a larger value of k = 0.0007 s-1 was obtained. We concluded that the rate of hydrolysis of (CH3)3CCl is directly proportional to water content in the solvent mixture.

Eventually using the NaOH and the acid’s consumed moles, the equivalent mass will be determined. Procedure: Part 2: Obtain 45mL of NaOH, and then weigh 0.3-0.4g of the unknown acid (KH2PO4). Dissolve the acid into 20.00mL water.

In certain cases, medical teams will be attach catheter into the urine bag. When necessary, is done filming the structure of kidney with CT (computed tomography) scans or Magnetic Resonance Imaging (MRI) scans and biopsies, that kidney tissue sampling. Causes Of Kidney Failure Diseases of the kidney failure is usually due to some serious disease that progressively damages organs that have an impact on sized in length ranging from 10-13 centimeters and a thickness 5 – 7.5 centimetres. There are several types of illnesses that can affect kidney damage, high blood pressure, diabetes mellitus, and blockage of the urinary tract. Diseases of the urinary tract blockages such as stones, tumors, and also causes narrowing of the kidney failure.

Once the time elapsed the tube was viewed and it changed from its green color to a dark blue color indicating a positive test. Based on these results the next test administrated was the motility test. A inculcating needle containing P. aeruginosa was placed into the motility medium using aseptic technique. The tube was then placed into an incubator at 37 degrees Celsius for 24 hours. After 24 hours passed the test was examined and growth was seen radiating from the stab line which indicated a positive test.

Five ml of reaction mixture 248 containing 50 mm phosphate buffer (pH 7.8), 13 mm methionine, 75 mm NBT, 2 mm 249 riboflavin, 0.1 mm EDTA and the enzyme extract. Absorbance of sample was read at 560 250 nm. The difference of percentage reduction of colour development in blank and the 251 sample was calculated. Fifty percent reduction in the colour was taken as one unit of 252 enzyme activity and was expressed in enzyme units per milligram protein (U mg-1 253 protein). 254 2.11.3.

The reaction that occurs can be investigated via the adding of the liver extract which contains the arginase to urea concentrations and distilled water. The amount of urea formed is determined via spectrophotometric analysis α-INPP. The urea produced was known via the color reaction with the α-INPP, it is the reagent used for the colorimetric determination of urea. (Barry J, et al. 1984). The red color formed when the α-INPP is reacted with the urea, is sensitive to light thus it is photo labile.

First, the 250-mL graduated cylinder, 100-mL graduated cylinder, and the 10-mL graduated cylinder were observed to see the volume of the liquid in each one. Then, one digit further was estimated, and the results were recorded. After that, the 25-mL graduated cylinder and the 50-mL beaker were cleaned and dried. Next, their masses were measured on the scale, and the results were rounded to the nearest thousands decimal place. Subsequently, the Erlenmeyer flask was filled with 100 mL of distilled water.

Objectives In this lab, you will investigate the percent composition by mass of CO2 in Alka-Seltzer® tablets. In addition, you will find out how much CO2 is released into the atmosphere as 2 Alka-Seltzer® tablets chemically react in vinegar. Procedure 250-mL beaker 100-mL graduated cylinder Scale 60 mL of Vinegar 2 Alka-Seltzer® tablets

What additional tests would you anticipate for W.A.? Ultrasound/CT Scan- To get a picture of the kidneys and urinary system. This will show the size of the kidneys whether or not there is kidney stones, tumors or cysts present.

The purpose of this experiment was to create two 40 mL buffers and evaluate its buffer capacity at pH 4. To do this, buffer #1 consisted of the mixture of 0.5003 M acetic acid and .50 M sodium acetate, while buffer #2 consisted of the mixture .5003 M acetic acid and .4289 M NaOH. Within each mixture, there is a ratio of conjugate acid to conjugate base. By using the Henderson Hasselbalch equation, the volume for the base and acid to buffer the pH of solution at 4.0 were calculated.

A Macroscopic analysis is done by making visual determination of color and clarity. These tests are done to check for the presence of disease, the color and smell of urine can indicate the presence of infection. To check the treatment in particular diseases like diabetes, kidney stones, high blood pressure, and liver and kidney disease to see if treatment is effective. Other
