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

------------------------------------------------- COLORIMETRIC DETERMINATION OF pH ------------------------------------------------- Abstract This experiment examined the result of the various color indicators combined with different buffer solution‚ thereby testing the precision and accuracy of determining the pH value colorimetrically. Colorimetric method is a simple and practical procedure with an important advantage: they do not get out of order as from time to time do the pH-meters. Four buffers (Acetate buffer‚ phosphate
