Introduction 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; meaning the amount of hydrogen

ECONOMIES OF SCALE When a firm moves from small scale to large scale production‚ the average cost of production of each unit falls. The reasons for which this happens are known as economies of scale – they are the benefits which result in the cost savings of large scale operations which come about when a firm expands. In other words‚ economies of scale are advantages reaped by firms engaging in large scale production. There are two types of economies of scale. They are: * Internal economies

Buffers‚ and pH‚ and Diffusion oh my The pH of a solution is the measure of the concentration of charged Hydrogen ions in that given solution. A solution with a pH lower than seven is considered to be acidic. A solution with a higher pH is a base. It is very important for organisms to maintain a stable pH. Biological molecules such as proteins function only at a certain pH level and any changes in pH can result in them not functioning properly. To maintain these constant pH levels‚ buffer solutions

University’s wooded areas‚ the oldest was created in 1989 the second was created in 1994 and the youngest plot was created in 1999. For the hypothesis to be tested‚ there were soil PH meters to test the amount of PH in each plot’s soil. The hypothesis was incorrect; there was not a significant difference in the means of the PH from the oldest plot compared to the youngest plot.

CIA III Psychological Measurement and Statistics Likert Scale: A Critical Analysis By‚ Mahika Sharma Likert Scale: A Critical Analysis Introduction The Likert Format arises from the scale for measuring attitudes (Kaplan‚ & Saccuzzo‚ 2001)‚ the first of which was originated in 1932 by Rensis Likert (Edmondson‚ 2005). The rationale behind development of the Likert Scale by Rensis Likert was to measure psychological attitudes in a “scientific” way in 1932 and later in 1934 to expand upon the scaling
