AMD Opteron. Opteron is AMD's x86 server and workstation processor line, particularly in the same segment as the Intel Xeon processor. In contrast to Intelâs Xeon line, AMDâs Opteron servers are tangibly cheaper, which make them an attractive option for the price conscious buyer looking for better performance per dollar.
Acid-Base Indicators and pH. Introduction. Acid-base indicators can be used to determine the pH of a solution. In this. experiment, you will prepare your own acid-base indicator by extracting a colored plant. pigment. Then you will use your indicator and others available in the lab to estimate the. pH of several other solutions.
pH Scale (pdf) A measure of the degree of the acidity or the alkalinity of a solution as measured on a scale (pH scale) of 0 to 14. The midpoint of 7.0 on the pH scale represents neutrality, i.e., a neutral solution is neither acid nor alkaline. Numbers below 7.0 indicate acidity; numbers greater than 7.0 indicate alkalinity. It is important to understand that pH is a measure of intensity, and not capacity; i.e., pH indicates the intensity of alkalinity in the same way temperature tells how hot something is, but not how much heat the substance carries.
