Chapter A1, Problem A1.20QAP

Interpretation Introduction

Interpretation:

The pH meter of range 2-12 can read standard deviation of $\pm 0.01\text{pH}$ units. The value of standard deviation of $[{\text{H}}_{\text{3}}{\text{O}}^{+}]$ is to be calculated at eachend of the range.

Concept introduction:

The following formula will be used for the calculation of the standard deviation in terms of antilogarithm-

$\frac{dx}{X}=2.303\times s_x$

Where,

$s_x$ = standard deviation in the pH

Or,

$X=-\text{anti}\log \text{pH}$
