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.
Depending on the pH of the product, you may be able to use paper pH strips (often. referred to as litmus paper), or required to use a pH meter. Paper strips that measure pH rely. on a color change in the paper to indicate product pH. Paper strips can be. used to measure pH if the product pH is less than 4.0.
