a measurement using a ph probe. arrange them in order from
first to last.
first
last
answer bank
place probe in solution to be measured.
rinse probe, then place in storage solution.
observe readout on meter of sample
solution ph.
remove probe from storage solution,
rinse probe.
calibrate probe using two or three buffers,
rinse probe.

Explanation:

First, the probe must be removed from the storage solution and rinsed to prepare it. Then, it should be calibrated using buffers. After calibration, it is placed in the solution to be measured. The pH is observed on the meter. Finally, the probe is rinsed and placed back in the storage solution.

Answer:

1. Remove probe from storage solution, rinse probe.
2. Calibrate probe using two or three buffers, rinse probe.
3. Place probe in solution to be measured.
4. Observe readout on meter of sample solution pH.
5. Rinse probe, then place in storage solution.
