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.
Each color on the key represents a different pH. An example of a used pH indicator stick and the corresponding color key is shown below in Figure 1. pH meters are electronic devices that used to measure pH. They consist of a probe that is dipped in a solution, and a digital readout. pH meters are even more precise than pH test paper or indicator sticks. Table 2 below discusses what types of pH measuring devices are best for different science project applications, and offers a quick link to ...
