Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

Today instead of learning to type‚ which was what people did a few years ago‚ students are taught word processing and keyboarding. More mature users who have been in the workforce for some years have had to learn word processing

of solutions and test their pH. Due to materials available pH strips were the only testing tools available. A table is setup to compare the strip color to its pH level. Four known solutions including bleach‚ lemon juice‚ soda‚ and baking soda were used. There was also an unknown solution in which the pH level was used to determine which solution it was. The pH scale is 1-14‚ a pH of 7 is neutral‚ less than 7 is acidic‚ and greater than 7 is acidic. Materials: * pH strips * 20 test tubes

BELOW THE KNEE AMPUTATION Below the knee amputation (BKA) is surgery to remove all or part of your foot or your leg below the knee cap. A below the knee amputation is a surgical procedure when the bottom part of the leg is removed with an incision below the knee. This is also known as a trans-tibial amputation. This procedure is recommended when a patient has a severely diseased or damaged lower leg that cannot be treated. Below-knee amputation is usually performed for extensive high-grade soft-tissue

pH and Chromatography Lab Report Kevin Rivera Biology Mr. Langley 2C 10/7/13 Introduction In this lab‚ of pH and Chromatography‚ in the pH aspect of the lab we are trying to figure out the pH level of certain chemicals by writing down of known solutions to find the type of unkown solution using pH standards. In the Chromatography‚ we are trying to separate the chemicals using water and a piece of paper. Methodology Materials: Safety Goggles pH indicator & pH indicator key

Question 1 Critique Dr. Honeydew’s report. Specifically‚ discuss what is missing and how the missing information should have been presented. First the PH measurements‚ Dr. honey dew does not explain how the PH device was calibrated or if the blood sample was added or mixed with anything prior to the measuring of the pH (like water‚ etc.). In regards to the absorption spectroscopy‚ the method by which the concentration was obtained is questionable. Was the concentration known before the experiment

Results In each condition‚ Appearance Evaluation and Body Areas Satisfaction Scale scores was transformed into Z-scores before summed and averaged into a single measure of appearance evaluation in accordance with the MBSRQ Users’ Manual (Cash‚ 2000). Checking for univariate outliers in the numeric rating scales (BAS-2‚ MBSRQ-AS‚ RSES) and subscales (AE‚ BASS) was done separately on the condition 1 and condition 2 dataset. Outliers was defined as scores above the sum of the interquartile range (IQR)
