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.
1 An acid-base indicator (e.g., phenolphthalein) changes color depending on the pH. 2  Redox indicators are also used. 3  A drop of indicator solution is added to the titration at the beginning; the endpoint has been reached when the color changes. Indicator: A substance that changes color in response to a chemical change. 2  An acid-base indicator (e.g., phenolphthalein) changes color depending on the pH. 3  Redox indicators are also used. 4  A drop of indicator solution is added to the titration at the beginning; the endpoint has been reached when the color changes.
