You aren't sure if your pH meter needs to be calibrated, so you put it in a buffer solution that has a known pH of 7. You take four separate readings of the solution with the pH meter. The meter reports the pH as 5.5, 8.6, 6.3, and 9.4. Were the measurements accurate, precise, neither, or both?

Answer :

Answer:

Neither

Explanation:

Even though the average between the 4 measurements is 7.45, the measurements are not accurate. This is probably due to the pH meter being out of calibration or because there is some contamination in the buffer solution

Neither of the measurement report is correct, because we know the pH of buffer is 7.

What if pH?

pH means potential hydrogen. PH is a measurement scale which measure the acidity and basicity of any solution.

The pH of pure water is 7.

The pH above 7 is acidic and the pH below 7 is basic.

In the given data, the pH of buffer is given already which is 7 and neither of the data is accurate to 7.

Correct option is neither of the data is accurate.
