An example would be pure water. Most of the time the pH is determined by pH paper but there are also other ways to determine the pH. For example, in this lab, cabbage juice was used. Cabbage juice is a great pH indicator because it can be homemade and easy to access.

PH sensors are used in many scientific laboratories to measure the hydrogen-ion concentration of a liquid substance and to determine the basicity and acidity of a liquid. PH meters measure the electrical potential difference between a reference electrode probe and a pH electrode probe. Since these probes are very sensitive, they are required to be kept cleansed from contaminants. If exposed to contamination, one risks faulty or unreliable data, since their accuracy is dependent on a regular calibration and upkeep. To avoid this risk, and accurately measure hydrogen-ion concentration, the probes are kept in a buffer solution and calibrated before each use. [1]

pH was recorded every time 1.00 mL of NaOH was added to beaker. When the amount of NaOH added to the beaker was about 5.00 mL away from the expected end point, NaOH was added very slowly. Approximately 0.20 mL of NaOH was added until the pH made a jump. The pH was recorded until it reached ~12. This was repeated two more times. The pKa of each trial are determined using the graphs made on excel.

In 2 and 7 I added 50 mL of .1 M NaCl. I added sodium acetate to the rest of the beakers: 1 gram to 3 and 8, 5 grams to 4 and 9, and 10 grams to 5 and 10. I then filled the beakers that contained the solid sodium acetate with 50 ml of .10 M acetic acid. Specifics can be found on page 84 of the lab manual. Though the lab manual instructed to use a pipet, we did not have an accurate 1 mL pipet or a graduated pipet, so we instead prepared two graduated burets with 1 M Sodium Hydroxide and 1 M hydrochloric acid. Using a standardized pH probe with a Lab Pro to measure changes in pH, we added 1 mL of HCl at a time and recorded the changes. The same was done for the NaOH.

twice. Place the pH probe in the beaker and record the pH in the data table. Drag the beaker to the red

That growth is likely to continue, driven by changes in healthcare delivery which are aimed at delivering less costly care closer to the patient’s home. In the developing world there is the challenge of more effective care for infectious diseases and PoCT may play a much greater role here in the future. PoCT technologies can be dividing into two categories: the first is small handheld devices, providing qualitative or quantitative determination of an increasing range of analytes. The technologies here are glucose biosensor strips and lateral flow strips using immobilised antibodies to determine a range of parameters including cardiac markers and infectious pathogens. The second categories of devices are larger, often bench-top devices which are essentially laboratory instruments which have been reduced in both size and complexity. These include critical care analysers and, more recently, small haematology and immunology analysers.

When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best results when testing the pH within a solution. The pH, which stands for the proportion of hydrogen ions in a solution, could be acidic (acidosis), neutral or basic (alkaline). The pH scale goes from numbers 1 through 14. A pH of 7 is neutral;

Medical technology is advancing at a rapid rate. For example, a very common procedure is an endoscopy and colonoscopy which checks for bowel and stomach cancers and some other conditions. New technology is being trialed at the moment, instead of a patient going under an anesthetic and having to have a special diet and bowel preparation prior to the procedure, this will now be done by taking a capsule in a tablet like form where the patient will swallow the capsule that contains a tiny camera and batteries and then be later eliminated by the patients natural bowel movements. This is swallowed by the patient and will travel through the gastro intestinal system, taking

Some people believe the doctors could care less about their patients getting addicted to the medicines they prescribe to them. The doctors in coal country believe in a “quick fix”, this allows the miners to go back to work rather than get the therapy they need to heel the injury. With the jobs these people have doctors aren’t doing what they’re supposed to do. However, the state became aware and cracked down on prescription rules and opened a prescription drug monitoring program. This program lead to the arrests of multiple doctors and pharmacist. Pill mills were a problem as well. Drug dealers moved in with pills from outside the state making the epidemic even worse. When it started to slow down, the prices rose and they began moving in heroin.

Water and Gatorade both had pH’s that eventually decreased. The three Gatorade urine samples started at a pH of 6.7 for the first measurement while the second and third both had a pH of 6.0. The urine samples from water had its first two measurements both at 6.5 and the third dropped to 6.0. Coke remained constant at 6.0 for all three measurements. The pH for coffee and the control increased over time. The pH for the first two of the coffee samples were both 6.5 and the third went up to 7.0. Lastly, the first control sample was 6.0 and went up to 6.5 for the second. (Figure

The purpose of this virtual lab is to observe the acid-base balance in the urinary system by how PCO2 and blood pH affect the H+ and HCO3- in the urine. The renal compensation is a mechanism that shows the kidneys manage to change pH in correct way if the respiratory system is not healthy. The kidneys are two organs that help remove wastes and extra fluids out of the body. The acid-base balance is when the blood need to keep the balance of

My science fair topic will be measuring the acidic levels in different companies of water bottles such as Aquafina, Dasani, Evian, Fiji, Miami Dade Tap Water, Penta, Publix Spring Water, Smart Water, Smart Water, Volvic, Voss, and Zephyrhills. Bottled water has been tested for its ppm (parts per million) to measure the amount of particles inside the water. The pH scale is a measurement of how acidic or basic an aqueous solution is. The pH scale has a range of 0-14; numbers less than 7 are considered acidic and numbers greater than 7 are considered basic. An acidic pH level means that the solution has more free hydrogen ions, and a basic pH level means that the solution has more free hydroxyl ions. pH is reported in logarithmic units and an increase or decrease of one on the pH scale has a 10-fold change. The negative logarithmic of the hydrogen ion concentration calculates the pH level of a solution. This is why pH stands for the potential of hydrogen and it calculate din

First, three titration curves and three second derivative curves were created to determine the average pH at the half-equivalence point from the acetic acid titrations. Titration curves were used as visuals to portray buffer capacity. The graphs and a table, Table 1, that showcased the values collected were created and included below. The flat region, the middle part, of Figures 1, 2 and 3, showed the zone at which the addition of a base or acid did not cause changes in pH. Once surpassed, the pH increased rapidly when a small amount of base, NaOH, was added to the buffer solution. Using the figures below and

There are many risks available with edible devices since we swallow them and take them inside to our body. Some of them are, what is long term impact of electronic communication through the body? How a device maintain patient compliance? What is the environmental impact of devices that may accumulate in wastewater treatment facility? Many of these questions have being answered in part by successful clinical testing of devices such as the pillCam and the Proteus Discover. One of the most significant risk elements is device retention within the GI tract[11].The risk associate with the device will depend on physical properties of the device and the disease state of the GI tract. Most devices have rigid polymeric coating to protect the electronic
