Learn What pH Stands For and How the Term Originated

Have you ever wondered what pH stands for or where the term originated? Here is the answer to the question and a look at the history of the pH scale. Key Takeaways: Origin of pH Term pH stands for power of hydrogen.The H is capitalized because it is the hydrogen element symbol.pH is a measure of how acidic or basic an aqueous solution is. It is calculated as the negative logarithm of hydrogen ion concentration. pH Definition and Origin pH is the negative log of hydrogen ion concentration in a water-based solution. The term pH was first described by Danish biochemist Sà ¸ren Peter Lauritz Sà ¸rensen in 1909. pH is an abbreviation for power of hydrogen where p is short for the German word for power, potenz and H is the element symbol for hydrogen. The H is capitalized because it is standard to capitalize element symbols. The abbreviation also works in French, with pouvoir hydrogen translating as the power of hydrogen. Logarithmic Scale The pH scale is a logarithmic scale that usually runs from 1 to 14. Each whole pH value below 7 (the pH of pure water) is ten times more acidic than the higher value and each whole pH value above 7 is ten times less acidic than the one below it. For example, a pH of 3 is ten times more acidic than a pH of 4 and 100 times (10 times 10) more acidic than a pH value of 5. So, a strong acid may have a pH of 1-2, while a strong base may have a pH of 13-14. A pH near 7 is considered to be neutral. Equation for pH pH is the logarithm of the hydrogen ion concentration of an aqueous (water-based) solution: pH -log[H] log is the base 10 logarithm and [H] is hydrogen ion concentration in the units moles per liter Its important to keep in mind a solution must be aqueous to have a pH. You cannot, for example, calculation pH of vegetable oil or pure ethanol. What Is the pH of Stomach Acid? | Can You Have Negative pH? Sources Bates, Roger G.  (1973).

1. Introduction. Reflective Practice Is A Key Part Of Working

1. Introduction Reflective practice is a key part of working as a health care professional, including speech and language therapists (SLT), and will be used throughout a practitioner’s career as part of their continuing professional development. It is the practice of experiencing situations and then reflecting on them, which is how clinicians may enhance their knowledge and skills and, thus, maintain their competence throughout their career as a practicing therapist (RCSLT, 2003). It is through this reflective practice that an SLT can progress â€Å"from novice to expert† (Tarrant, 2013; p3). Furthermore, reflective practice is a skill which itself continues to be developed. Reflective practice and professional development are intrinsically†¦show more content†¦This can be particularly useful in holistic practices used by SLTs where knowledge gained from other situations and clients may not be appropriate in the current situation; prior preconceptions about a client may lead to an unexpected outcome that may need to be rectified. The ability to reflect on an on-going experience will allow the clinician to correct their practices within that situation. To reflect in action is something all practitioners do; it is a form of professional instinct. In some cases, this may be as simple as monitoring the level of language used and ensuring it is appropriate for the specific client. However, to truly monitor and adapt practices simultaneously requires a level of expertise that a novice SLT may not yet have (Findlay, 2008), as they are more likely to need to detach themselves from the situation, requiring more time to process situations. 2.2. Reflective Cycle (Gibbs, 1988) The model provides six stages in which a professional may reflect upon their experiences. It focuses on the medium of written reflection and comprises: (1) a description of the event; (2) a description of emotional responses; (3) consideration of the emotional response; (4) analysis, including academic research, to understand the situation; (5) conclusions drawn from the experience; and (6) future strategies.

Title Of Paper Auschwitz The Nazi Concentration Camp Essays

Title of Paper : Auschwitz the Nazi Concentration Camp Grade Received on Report : 100 AUSCHWITZ THE NAZI CONCENTRATION CAMP Located thirty-seven miles west of Krakow, Auschwitz was the camp where Jewish people were killed and worked. This camp , out of all the rest tortured the most people. At the camp there was a place called the "Black Wall," this was where the people were executed . In March of 1941, there was another camp that started to be built. This second camp was called Auschwitz II, or Birkinau. It was located 1.9 miles away from Auschwitz I. People that were chosen to come to these camps were expelled from their homes. Their houses were destroyed for the purpose of building Birkinau. Birkinau had nine sub-units. They were separated from each other by electrically charged fences that lines their borders. In August 1942, the womens' section at Auscwitz I was moved to Birkinau. Nine hundred and ninety-nine women from Ravensbruck camp and other women from different camps joined them also. Birkinau now had over 6,000 women prisoners being held. In the town Monowitz, another camp w! as being built. This camp was called Auschwitz III, or Buna-Monowitz. Other camps that were located close to Monowitz were moved to Buna-Monowitz. The population of Birknau was the most densly populated out of all the camps. It also had the most cruel and bad conditions of all the camps in the complex. The prisoners at Birkinau mostly consisted of Jews, Poles , and Germans. There were a number of Gypsy and Czech Jew family camps located at Birkinau for a period of time also. In Birkinau, the gas chambers and the oven, where the bodies were burned operated at Auschwitz I. Birkinau and all the other sub-camps were mostly forced labor camps. The most recognized of the labor camps are, Budy, Czechowitz, Glenwitz, Rajsko, and Furstenarube. The prisoners here were worked to the point of death. Trains transported people to the camps, and violently forced them off the train. All of the people's property was left on the train also. They prisoners were sent into two different! lines, one for women and the other for men. The lines moved into the place were a procedure called ?Selection' took place. The ones who could work were not killed at this time, but the women, children, and others that couldn't work were gassed. The prisoners that were to work, had their clothes taken, heads shaved, got sterilized, and were given black and white striped clothes to wear. In the forced labor camps, the average life time was only a few months. Some of the prisoners that couldn't react or move became what was known as Muselmann. A dreaded part of camps was the Appeal, or roll call. In this, prisoners were sent out into the cold night after a hard day of work, and lined up. Anyone that fell to the ground was shot or gassed. One more of all the bad work chores was the Sonderkommando. Dong this meant that you burned the bodies of the dead prisoners in the creamatoria. Tattoos were given to the prisoners on their right arm as an easier way of registration. ! Not all of the earlier prisoners had this tattoo, but the regiterd number of prisoners was 405,000. The daily routine in the complex differed in each camp, but the basic routine was the same. They: woke at dawn, cleaned their areas, morning roll call was taken, they walked to the work site, worked for long hours, had to wait in lines for food, then walked bback to their bunks, block inspection was done, and then evening roll call was taken. There were also people who got picked for medical experiments. The best known docter at Auschwitz was Josef Mengele. His experiments were mostly done on twins and dwarfs. He did lots of things that had to do with seeing how ling it would take a person to die if you do this or that. He also did experiments that had to do with cutting off body parts, and reattaaching them to different parts of the body. By January 20th, 1944, the population of the Aushwitz complex had reached 80,839. That number rose up and up as the monthes past an! d more prisoners came. The first gas chamber to be used was bult in Auschwitz I. The gas that was used in the chambers was called Zyklon B. In
