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.
An acid-base indicator is a weak acid or a weak base. The undissociated form of the indicator is a different color than the iogenic form of the indicator. An Indicator does not change color from pure acid to pure alkaline at specific hydrogen ion concentration, but rather, color change occurs over a range of hydrogen ion concentrations. This range is termed the color change interval. It is expressed as a pH range.
