WebSodium methoxide is a routinely used base in organic chemistry, applicable to the synthesis of numerous compounds ranging from pharmaceuticals to agrichemicals. [4] As a base, it is employed in dehydrohalogenations and various condensations. [5] It is also a nucleophile for the production of methyl ethers. [6] WebspHX). Since sEo is unknown, determining s spHX from the measured sE X requires cell calibration by a standard solution of assigned s spHS (see 3.5.4 for the determination of s spHS), which requires replacing the sample solution at s spHX in cell (XI) by the standard solution at s spHS and measuring the e.m.f. sE S of the resulting cell (XII):
